@chapter String and Array Utilities

Operations on strings (or arrays of characters) are an important part of
|
|
|
|
many programs. The GNU C library provides an extensive set of string
|
|
|
|
utility functions, including functions for copying, concatenating,
|
|
|
|
comparing, and searching strings. Many of these functions can also
|
|
|
|
operate on arbitrary regions of storage; for example, the @code{memcpy}
|
1996-08-09 04:46:09 +02:00
|
|
|
function can be used to copy the contents of any kind of array.

|
|
|
|
|
|
|
It's fairly common for beginning C programmers to ``reinvent the wheel''
|
|
|
|
by duplicating this functionality in their own code, but it pays to
|
|
|
|
become familiar with the library functions and to make use of them,
|
|
|
|
since this offers benefits in maintenance, efficiency, and portability.
|
|
|
|
|
|
|
|
For instance, you could easily compare one string to another in two
|
|
|
|
lines of C code, but if you use the built-in @code{strcmp} function,
|
|
|
|
you're less likely to make a mistake. And, since these library
|
|
|
|
functions are typically highly optimized, your program may run faster
|
|
|
|
too.

@section Representation of Strings
|

@cindex string, representation of
|
|
|
|
|
|
|
|
This section is a quick summary of string concepts for beginning C
|
|
|
|
programmers. It describes how character strings are represented in C
|
|
|
|
and some common pitfalls. If you are already familiar with this
|
|
|
|
material, you can skip this section.

@cindex string
|
2001-02-11 02:50:24 +01:00
|
|
|
@cindex multibyte character string
|
1995-02-18 02:27:10 +01:00
|
|
|
A @dfn{string} is an array of @code{char} objects. But string-valued
|
|
|
|
variables are usually declared to be pointers of type @code{char *}.
|
|
|
|
Such variables do not include space for the text of a string; that has
|
|
|
|
to be stored somewhere else---in an array variable, a string constant,
|
|
|
|
or dynamically allocated memory (@pxref{Memory Allocation}). It's up to
|
|
|
|
you to store the address of the chosen memory space into the pointer
|
|
|
|
variable. Alternatively you can store a @dfn{null pointer} in the
|
|
|
|
pointer variable. The null pointer does not point anywhere, so
|
|
|
|
attempting to reference the string it points to gets an error.
|
|
|
|
|
2001-02-11 02:50:24 +01:00
|
|
|
@cindex wide character string
|
|
|
|
``string'' normally refers to multibyte character strings as opposed to
|
|
|
|
wide character strings. Wide character strings are arrays of type
|
|
|
|
@code{wchar_t} and as for multibyte character strings usually pointers
|
|
|
|
of type @code{wchar_t *} are used.
|
|
|
|
|
|
|
|
@cindex null character
|
|
|
|
@cindex null wide character
|
1995-02-18 02:27:10 +01:00
|
|
|
By convention, a @dfn{null character}, @code{'\0'}, marks the end of a
|
2001-02-11 02:50:24 +01:00
|
|
|
multibyte character string and the @dfn{null wide character},
|
|
|
|
@code{L'\0'}, marks the end of a wide character string. For example, in
|
|
|
|
testing to see whether the @code{char *} variable @var{p} points to a
|
|
|
|
null character marking the end of a string, you can write
|
|
|
|
@code{!*@var{p}} or @code{*@var{p} == '\0'}.
|
1995-02-18 02:27:10 +01:00
|
|
|
|
|
|
|
A null character is quite different conceptually from a null pointer,
|
|
|
|
although both are represented by the integer @code{0}.
|
|
|
|
|
|
|
|
@cindex string literal
|
|
|
|
@dfn{String literals} appear in C program source as strings of
|
2001-02-11 02:50:24 +01:00
|
|
|
characters between double-quote characters (@samp{"}) where the initial
|
|
|
|
double-quote character is immediately preceded by a capital @samp{L}
|
|
|
|
(ell) character (as in @code{L"foo"}). In @w{ISO C}, string literals
|
|
|
|
can also be formed by @dfn{string concatenation}: @code{"a" "b"} is the
|
|
|
|
same as @code{"ab"}. For wide character strings one can either use
|
|
|
|
@code{L"a" L"b"} or @code{L"a" "b"}. Modification of string literals is
|
|
|
|
not allowed by the GNU C compiler, because literals are placed in
|
|
|
|
read-only storage.
|
1995-02-18 02:27:10 +01:00
|
|
|
|
|
|
|
Character arrays that are declared @code{const} cannot be modified
|
|
|
|
either. It's generally good style to declare non-modifiable string
|
|
|
|
pointers to be of type @code{const char *}, since this often allows the
|
|
|
|
C compiler to detect accidental modifications as well as providing some
|
|
|
|
amount of documentation about what your program intends to do with the
|
|
|
|
string.
|
|
|
|
|
|
|
|
The amount of memory allocated for the character array may extend past
|
|
|
|
the null character that normally marks the end of the string. In this

document, the term @dfn{allocated size} is always used to refer to the
|
1995-02-18 02:27:10 +01:00
|
|
|
total amount of memory allocated for the string, while the term
|
|
|
|
@dfn{length} refers to the number of characters up to (but not
|
|
|
|
including) the terminating null character.

A notorious source of program bugs is trying to put more characters in a
|
|
|
|
string than fit in its allocated size. When writing code that extends
|
|
|
|
strings or moves characters into a pre-allocated array, you should be
|
|
|
|
very careful to keep track of the length of the text and make explicit
|
|
|
|
checks for overflowing the array. Many of the library functions
|
|
|
|
@emph{do not} do this for you! Remember also that you need to allocate
|
|
|
|
an extra byte to hold the null character that marks the end of the
|
|
|
|
string.

@cindex single-byte string
|
|
|
|
@cindex multibyte string
|
|
|
|
Originally strings were sequences of bytes where each byte represents a
|
|
|
|
single character. This is still true today if the strings are encoded
|
|
|
|
using a single-byte character encoding. Things are different if the
|
|
|
|
strings are encoded using a multibyte encoding (for more information on
|
|
|
|
encodings see @ref{Extended Char Intro}). There is no difference in
|
|
|
|
the programming interface for these two kind of strings; the programmer
|
|
|
|
has to be aware of this and interpret the byte sequences accordingly.
|
|
|
|
|
|
|
|
But since there is no separate interface taking care of these
|
|
|
|
differences the byte-based string functions are sometimes hard to use.
|
|
|
|
Since the count parameters of these functions specify bytes a call to
|
|
|
|
@code{strncpy} could cut a multibyte character in the middle and put an
|
|
|
|
incomplete (and therefore unusable) byte sequence in the target buffer.
|
|
|
|
|
|
|
|
@cindex wide character string
|
|
|
|
To avoid these problems later versions of the @w{ISO C} standard
|
|
|
|
introduce a second set of functions which are operating on @dfn{wide
|
|
|
|
characters} (@pxref{Extended Char Intro}). These functions don't have
|
|
|
|
the problems the single-byte versions have since every wide character is
|
|
|
|
a legal, interpretable value. This does not mean that cutting wide
|
|
|
|
character strings at arbitrary points is without problems. It normally
|
|
|
|
is for alphabet-based languages (except for non-normalized text) but
|
|
|
|
languages based on syllables still have the problem that more than one
|
|
|
|
wide character is necessary to complete a logical unit. This is a
|
|
|
|
higher level problem which the @w{C library} functions are not designed
|
|
|
|
to solve. But it is at least good that no invalid byte sequences can be
|
|
|
|
created. Also, the higher level functions can also much easier operate
|
|
|
|
on wide character than on multibyte characters so that a general advise
|
|
|
|
is to use wide characters internally whenever text is more than simply
|
|
|
|
copied.
|
|
|
|
|
|
|
|
The remaining of this chapter will discuss the functions for handling
|
|
|
|
wide character strings in parallel with the discussion of the multibyte
|
|
|
|
character strings since there is almost always an exact equivalent
|
|
|
|
available.

@section String and Array Conventions
|

|

This chapter describes both functions that work on arbitrary arrays or
|
|
|
|
blocks of memory, and functions that are specific to null-terminated
|
2001-02-11 02:50:24 +01:00
|
|
|
arrays of characters and wide characters.
|
1995-02-18 02:27:10 +01:00
|
|
|
|
|
|
|
Functions that operate on arbitrary blocks of memory have names
|
2001-02-11 02:50:24 +01:00
|
|
|
beginning with @samp{mem} and @samp{wmem} (such as @code{memcpy} and
|
|
|
|
@code{wmemcpy}) and invariably take an argument which specifies the size
|
|
|
|
(in bytes and wide characters respectively) of the block of memory to
|
1995-02-18 02:27:10 +01:00
|
|
|
operate on. The array arguments and return values for these functions
|
2001-02-11 02:50:24 +01:00
|
|
|
have type @code{void *} or @code{wchar_t}. As a matter of style, the
|
|
|
|
elements of the arrays used with the @samp{mem} functions are referred
|
|
|
|
to as ``bytes''. You can pass any kind of pointer to these functions,
|
|
|
|
and the @code{sizeof} operator is useful in computing the value for the
|
|
|
|
size argument. Parameters to the @samp{wmem} functions must be of type
|
|
|
|
@code{wchar_t *}. These functions are not really usable with anything
|
|
|
|
but arrays of this type.
|
|
|
|
|
|
|
|
In contrast, functions that operate specifically on strings and wide
|
|
|
|
character strings have names beginning with @samp{str} and @samp{wcs}
|
|
|
|
respectively (such as @code{strcpy} and @code{wcscpy}) and look for a
|
|
|
|
null character to terminate the string instead of requiring an explicit
|
|
|
|
size argument to be passed. (Some of these functions accept a specified
|
1995-02-18 02:27:10 +01:00
|
|
|
maximum length, but they also check for premature termination with a
|
|
|
|
null character.) The array arguments and return values for these
|
2001-02-11 02:50:24 +01:00
|
|
|
functions have type @code{char *} and @code{wchar_t *} respectively, and
|
|
|
|
the array elements are referred to as ``characters'' and ``wide
|
|
|
|
characters''.
|
|
|
|
|
|
|
|
In many cases, there are both @samp{mem} and @samp{str}/@samp{wcs}
|
|
|
|
versions of a function. The one that is more appropriate to use depends
|
|
|
|
on the exact situation. When your program is manipulating arbitrary
|
|
|
|
arrays or blocks of storage, then you should always use the @samp{mem}
|
|
|
|
functions. On the other hand, when you are manipulating null-terminated
|
|
|
|
strings it is usually more convenient to use the @samp{str}/@samp{wcs}
|
|
|
|
functions, unless you already know the length of the string in advance.
|
|
|
|
The @samp{wmem} functions should be used for wide character arrays with
|
|
|
|
known size.
|
|
|
|
|
|
|
|
@cindex wint_t
|
|
|
|
@cindex parameter promotion
|
|
|
|
Some of the memory and string functions take single characters as
|
|
|
|
arguments. Since a value of type @code{char} is automatically promoted
|
|
|
|
into an value of type @code{int} when used as a parameter, the functions
|
|
|
|
are declared with @code{int} as the type of the parameter in question.
|
|
|
|
In case of the wide character function the situation is similarly: the
|
|
|
|
parameter type for a single wide character is @code{wint_t} and not
|
|
|
|
@code{wchar_t}. This would for many implementations not be necessary
|
|
|
|
since the @code{wchar_t} is large enough to not be automatically
|
|
|
|
promoted, but since the @w{ISO C} standard does not require such a
|
|
|
|
choice of types the @code{wint_t} type is used.

But beware, this will not work unless @var{string} is the character
|
|
|
|
array itself, not a pointer to it. For example:
|
|
|
|
|
|
|
|
@smallexample
|
|
|
|
char string[32] = "hello, world";
|
|
|
|
char *ptr = string;
|
|
|
|
sizeof (string)
|
|
|
|
@result{} 32
|
|
|
|
sizeof (ptr)
|
|
|
|
@result{} 4 /* @r{(on a machine with 4 byte pointers)} */
|
|
|
|
@end smallexample
|
|
|
|
|
|
|
|
This is an easy mistake to make when you are working with functions that
|
|
|
|
take string arguments; those arguments are always pointers, not arrays.
|
|
|
|
|
2001-02-11 02:50:24 +01:00
|
|
|
It must also be noted that for multibyte encoded strings the return
|
|
|
|
value does not have to correspond to the number of characters in the
|
|
|
|
string. To get this value the string can be converted to wide
|
|
|
|
characters and @code{wcslen} can be used or something like the following
|
|
|
|
code can be used:
|
|
|
|
|
|
|
|
@smallexample
|
|
|
|
/* @r{The input is in @code{string}.}
|
|
|
|
@r{The length is expected in @code{n}.} */
|
|
|
|
@{
|
|
|
|
mbstate_t t;
|
|
|
|
char *scopy = string;
|
|
|
|
/* In initial state. */
|
|
|
|
memset (&t, '\0', sizeof (t));
|
|
|
|
/* Determine number of characters. */
|
|
|
|
n = mbsrtowcs (NULL, &scopy, strlen (scopy), &t);
|
|
|
|
@}
|
|
|
|
@end smallexample
|
|
|
|
|
|
|
|
This is cumbersome to do so if the number of characters (as opposed to
|
|
|
|
bytes) is needed often it is better to work with wide characters.
|
|
|
|
@end deftypefun

@deftypefun size_t wcslen (const wchar_t *@var{ws})
|
|
|
|
The @code{wcslen} function is the wide character equivalent to
|
|
|
|
@code{strlen}. The return value is the number of wide characters in the
|
|
|
|
wide character string pointed to by @var{ws} (this is also the offset of
|
|
|
|
the terminating null wide character of @var{ws}).
|
|
|
|
|
|
|
|
Since there are no multi wide character sequences making up one
|
|
|
|
character the return value is not only the offset in the array, it is
|
|
|
|
also the number of wide characters.

|
The @code{strnlen} function returns the length of the string @var{s} in
|
|
|
|
bytes if this length is smaller than @var{maxlen} bytes. Otherwise it
|

returns @var{maxlen}. Therefore this function is equivalent to

another. The @samp{str} and @samp{mem} functions are declared in the

|

A helpful way to remember the ordering of the arguments to the functions
|
|
|
|
in this section is that it corresponds to an assignment expression, with
|
|
|
|
the destination array specified to the left of the source array. All
|
|
|
|
of these functions return the address of the destination array.
|
|
|
|
|
|
|
|
Most of these functions do not work properly if the source and
|
|
|
|
destination arrays overlap. For example, if the beginning of the
|
|
|
|
destination array overlaps the end of the source array, the original
|
|
|
|
contents of that part of the source array may get overwritten before it
|
|
|
|
is copied. Even worse, in the case of the string functions, the null
|
|
|
|
character marking the end of the string may be lost, and the copy
|
|
|
|
function might get stuck in a loop trashing all the memory allocated to
|
|
|
|
your program.
|
|
|
|
|
|
|
|
All functions that have problems copying between overlapping arrays are
|
|
|
|
explicitly identified in this manual. In addition to functions in this
|
|
|
|
section, there are a few others like @code{sprintf} (@pxref{Formatted
|
|
|
|
Output Functions}) and @code{scanf} (@pxref{Formatted Input

The @code{wmemcpy} function copies @var{size} wide characters from the object

beginning at @var{wfrom} into the object beginning at @var{wto}. The

The @code{mempcpy} function is nearly identical to the @code{memcpy}

function. It copies @var{size} bytes from the object beginning at

|
|

@code{from} into the object pointed to by @var{to}. But instead of
|
1999-11-02 00:01:49 +01:00
|
|
|
returning the value of @var{to} it returns a pointer to the byte
|
1997-09-16 23:51:15 +02:00
|
|
|
following the last written byte in the object beginning at @var{to}.
|

|
|
I.e., the value is @code{((void *) ((char *) @var{to} + @var{size}))}.

This function is useful in situations where a number of objects shall be

|
|
|
|
The @code{wmempcpy} function is nearly identical to the @code{wmemcpy}
|
|
|
|
function. It copies @var{size} wide characters from the object
|
|
|
|
beginning at @code{wfrom} into the object pointed to by @var{wto}. But
|
|
|
|
instead of returning the value of @var{wto} it returns a pointer to the
|
|
|
|
wide character following the last written wide character in the object
|
|
|
|
beginning at @var{wto}. I.e., the value is @code{@var{wto} + @var{size}}.
|
|
|
|
|
|
|
|
This function is useful in situations where a number of objects shall be
|
|
|
|
copied to consecutive memory positions.
|
|
|
|
|
|
|
|
The following is a possible implementation of @code{wmemcpy} but there
|

are more optimizations possible.

The behavior of @code{strncpy} is undefined if the strings overlap.

Using @code{strncpy} as opposed to @code{strcpy} is a way to avoid bugs

However, it can also make your program much slower in one common case:

copying a string which is probably small into a potentially large buffer.

In this case, @var{size} may be large, and when it is, @code{strncpy} will

For obvious reasons @code{strdupa} is implemented only as a macro;

1997-08-20 05:53:21 +02:00

you cannot get the address of this function. Despite this limitation
|
1996-08-15 03:23:29 +02:00
|
|

it is a useful function. The following code shows a situation where

using @code{malloc} would be a lot more expensive.

Please note that calling @code{strtok} using @var{path} directly is

2001-02-11 02:50:24 +01:00

invalid. It is also not allowed to call @code{strdupa} in the argument
|
|
|
|
list of @code{strtok} since @code{strdupa} uses @code{alloca}
|
|
|
|
(@pxref{Variable Size Automatic}) can interfere with the parameter
|
|
|
|
passing.

Programmers using the @code{strcat} or @code{wcscat} function (or the
|
|
|
|
following @code{strncat} or @code{wcsncar} functions for that matter)
|
|
|
|
can easily be recognized as lazy and reckless. In almost all situations
|
|
|
|
the lengths of the participating strings are known (it better should be
|
|
|
|
since how can one otherwise ensure the allocated size of the buffer is
|
|
|
|
sufficient?) Or at least, one could know them if one keeps track of the
|
1999-01-27 01:11:04 +01:00
|
|
|
results of the various function calls. But then it is very inefficient
|
2001-02-11 02:50:24 +01:00
|
|
|
to use @code{strcat}/@code{wcscat}. A lot of time is wasted finding the
|
|
|
|
end of the destination string so that the actual copying can start.
|
|

This looks quite simple, especially the second loop where the strings
|
|
|
|
are actually copied. But these innocent lines hide a major performance
|
|
|
|
penalty. Just imagine that ten strings of 100 bytes each have to be
|
|
|
|
concatenated. For the second string we search the already stored 100
|
|
|
|
bytes for the end of the string so that we can append the next string.
|
|
|
|
For all strings in total the comparisons necessary to find the end of
|
|
|
|
the intermediate results sums up to 5500! If we combine the copying
|
|
|
|
with the search for the allocation we can write this function more

With a bit more knowledge about the input strings one could fine-tune
|
|
|
|
the memory allocation. The difference we are pointing to here is that
|
|
|
|
we don't use @code{strcat} anymore. We always keep track of the length
|
|
|
|
of the current intermediate result so we can safe us the search for the
|
|
|
|
end of the string and use @code{mempcpy}. Please note that we also
|
|
|
|
don't use @code{stpcpy} which might seem more natural since we handle
|
|
|
|
with strings. But this is not necessary since we already know the
|
|
|
|
length of the string and therefore can use the faster memory copying
|
2001-02-11 02:50:24 +01:00
|
|
|
function. The example would work for wide characters the same way.
|
1999-01-27 01:11:04 +01:00
|
|
|
|
|
|
|
Whenever a programmer feels the need to use @code{strcat} she or he
|
|
|
|
should think twice and look through the program whether the code cannot
|
|
|
|
be rewritten to take advantage of already calculated results. Again: it
|
|
|
|
is almost always unnecessary to use @code{strcat}.

You can use the functions in this section to perform comparisons on the
|
|
|
|
contents of strings and arrays. As well as checking for equality, these
|
|
|
|
functions can also be used as the ordering functions for sorting
|
|
|
|
operations. @xref{Searching and Sorting}, for an example of this.
|
|
|
|
|
|
|
|
Unlike most comparison operations in C, the string comparison functions
|
|
|
|
return a nonzero value if the strings are @emph{not} equivalent rather
|
|
|
|
than if they are. The sign of the value indicates the relative ordering
|
|
|
|
of the first characters in the strings that are not equivalent: a
|
|
|
|
negative value indicates that the first string is ``less'' than the
|
1996-08-09 04:46:09 +02:00
|
|
|
second, while a positive value indicates that the first string is
|
1995-02-18 02:27:10 +01:00
|
|
|
``greater''.
|
|
|
|
|
|
|
|
The most common use of these functions is to check only for equality.
|
|
|
|
This is canonically done with an expression like @w{@samp{! strcmp (s1, s2)}}.
|
|
|
|
|
|
|
|
All of these functions are declared in the header file @file{string.h}.

@deftypefun int memcmp (const void *@var{a1}, const void *@var{a2}, size_t @var{size})

The function @code{memcmp} compares the @var{size} bytes of memory
|
|
|
|
beginning at @var{a1} against the @var{size} bytes of memory beginning
|
|
|
|
at @var{a2}. The value returned has the same sign as the difference

@code{0}.

@deftypefun int wmemcmp (const wchar_t *@var{a1}, const wchar_t *@var{a2}, size_t @var{size})
|
|
|
|
The function @code{wmemcmp} compares the @var{size} wide characters
|
|
|
|
beginning at @var{a1} against the @var{size} wide characters beginning
|
|
|
|
at @var{a2}. The value returned is smaller than or larger than zero
|
|
|
|
depending on whether the first differing wide character is @var{a1} is
|
|
|
|
smaller or larger than the corresponding character in @var{a2}.
|
|
|
|
|
|
|
|
If the contents of the two blocks are equal, @code{wmemcmp} returns
|
|
|
|
@code{0}.

1995-02-18 02:27:10 +01:00
|
|
|
On arbitrary arrays, the @code{memcmp} function is mostly useful for
|
|
|
|
testing equality. It usually isn't meaningful to do byte-wise ordering
|
|
|
|
comparisons on arrays of things other than bytes. For example, a
|
|
|
|
byte-wise comparison on the bytes that make up floating-point numbers
|
|
|
|
isn't likely to tell you anything about the relationship between the
|
|
|
|
values of the floating-point numbers.
|
|
|
|
|
2001-02-11 02:50:24 +01:00
|
|
|
@code{wmemcmp} is really only useful to compare arrays of type
|
|
|
|
@code{wchar_t} since the function looks at @code{sizeof (wchar_t)} bytes
|
|
|
|
at a time and this number of bytes is system dependent.
|
|
|
|
|
1995-02-18 02:27:10 +01:00
|
|
|
You should also be careful about using @code{memcmp} to compare objects
|
|
|
|
that can contain ``holes'', such as the padding inserted into structure
|
|
|
|
objects to enforce alignment requirements, extra space at the end of
|
|
|
|
unions, and extra characters at the ends of strings whose length is less
|
|
|
|
than their allocated size. The contents of these ``holes'' are
|
|
|
|
indeterminate and may cause strange behavior when performing byte-wise
|
|
|
|
comparisons. For more predictable results, perform an explicit
|
|
|
|
component-wise comparison.
|
|
|
|
|
|
|
|
For example, given a structure type definition like:
|
|
|
|
|
|
|
|
@smallexample
|
|
|
|
struct foo
|
|
|
|
@{
|
|
|
|
unsigned char tag;
|
|
|
|
union
|
|
|
|
@{
|
|
|
|
double f;
|
|
|
|
long i;
|
|
|
|
char *p;
|
|
|
|
@} value;
|
|
|
|
@};
|
|
|
|
@end smallexample
|
|
|
|
|
|
|
|
@noindent
|
|
|
|
you are better off writing a specialized comparison function to compare
|
|
|
|
@code{struct foo} objects instead of comparing them with @code{memcmp}.

@deftypefun int strcmp (const char *@var{s1}, const char *@var{s2})
|
|
|

The @code{strcmp} function compares the string @var{s1} against
|
|
|
|
@var{s2}, returning a value that has the same sign as the difference
|

If the two strings are equal, @code{strcmp} returns @code{0}.

A consequence of the ordering used by @code{strcmp} is that if @var{s1}

@code{strncmp} (equivalent examples can be constructed for the wide

@var{s2}, considering them as holding indices/version numbers. The

|
|
|
|
|
|
|
|
In some locales, the conventions for lexicographic ordering differ from
|
|
|
|
the strict numeric ordering of character codes. For example, in Spanish
|
|
|
|
most glyphs with diacritical marks such as accents are not considered
|
|
|
|
distinct letters for the purposes of collation. On the other hand, the
|
|
|
|
two-character sequence @samp{ll} is treated as a single letter that is
|
|
|
|
collated immediately after @samp{l}.
|
|
|
|
|
|
|
|
You can use the functions @code{strcoll} and @code{strxfrm} (declared in
|
2001-02-11 02:50:24 +01:00
|
|
|
the headers file @file{string.h}) and @code{wcscoll} and @code{wcsxfrm}
|
|
|
|
(declared in the headers file @file{wchar}) to compare strings using a
|
|
|
|
collation ordering appropriate for the current locale. The locale used
|
|
|
|
by these functions in particular can be specified by setting the locale
|
|
|
|
for the @code{LC_COLLATE} category; see @ref{Locales}.

|
1995-02-18 02:27:10 +01:00
|
|
|
|
|
|
|
In the standard C locale, the collation sequence for @code{strcoll} is
|
2001-02-11 02:50:24 +01:00
|
|
|
the same as that for @code{strcmp}. Similarly, @code{wcscoll} and
|
|
|
|
@code{wcscmp} are the same in this situation.
|
1995-02-18 02:27:10 +01:00
|
|
|
|
|
|
|
Effectively, the way these functions work is by applying a mapping to
|
|
|
|
transform the characters in a string to a byte sequence that represents
|
|
|
|
the string's position in the collating sequence of the current locale.
|
|
|
|
Comparing two such byte sequences in a simple fashion is equivalent to
|
|
|
|
comparing the strings with the locale's collating sequence.
|
|
|
|
|
2001-02-11 02:50:24 +01:00
|
|
|
The functions @code{strcoll} and @code{wcscoll} perform this translation
|
|
|
|
implicitly, in order to do one comparison. By contrast, @code{strxfrm}
|
|
|
|
and @code{wcsxfrm} perform the mapping explicitly. If you are making
|
|
|
|
multiple comparisons using the same string or set of strings, it is
|
|
|
|
likely to be more efficient to use @code{strxfrm} or @code{wcsxfrm} to
|
|
|
|
transform all the strings just once, and subsequently compare the
|
|
|
|
transformed strings with @code{strcmp} or @code{wcscmp}.

Here is an example of sorting an array of strings, using @code{strcoll}
|
|
|
|
to compare them. The actual sort algorithm is not written here; it
|
|
|
|
comes from @code{qsort} (@pxref{Array Sort Function}). The job of the
|
|
|
|
code shown here is to say how to compare the strings while sorting them.
|
|
|
|
(Later on in this section, we will show a way to do this more
|
|
|
|
efficiently using @code{strxfrm}.)

@deftypefun size_t strxfrm (char *restrict @var{to}, const char *restrict @var{from}, size_t @var{size})
|
|
|
|
The function @code{strxfrm} transforms the string @var{from} using the
|
|
|
|
collation transformation determined by the locale currently selected for
|
1995-02-18 02:27:10 +01:00
|
|
|
collation, and stores the transformed string in the array @var{to}. Up
|
|
|
|
to @var{size} characters (including a terminating null character) are
|
|
|
|
stored.
|
|
|
|
|
|
|
|
The behavior is undefined if the strings @var{to} and @var{from}
|
|
|
|
overlap; see @ref{Copying and Concatenation}.
|
|
|
|
|
|
|
|
The return value is the length of the entire transformed string. This
|
|
|
|
value is not affected by the value of @var{size}, but if it is greater
|
1996-08-09 04:46:09 +02:00
|
|
|
or equal than @var{size}, it means that the transformed string did not
|
|
|
|
entirely fit in the array @var{to}. In this case, only as much of the
|
|
|
|
string as actually fits was stored. To get the whole transformed
|
|
|
|
string, call @code{strxfrm} again with a bigger output array.
|
1995-02-18 02:27:10 +01:00
|
|
|
|
|
|
|
The transformed string may be longer than the original string, and it
|
|
|
|
may also be shorter.
|
|
|
|
|
|
|
|
If @var{size} is zero, no characters are stored in @var{to}. In this
|
|
|
|
case, @code{strxfrm} simply returns the number of characters that would
|
|
|
|
be the length of the transformed string. This is useful for determining
|
2001-02-11 02:50:24 +01:00
|
|
|
what size the allocated array should be. It does not matter what
|
|
|
|
@var{to} is if @var{size} is zero; @var{to} may even be a null pointer.

|
The function @code{wcsxfrm} transforms wide character string @var{wfrom}
|
|
|
|
using the collation transformation determined by the locale currently
|
|
|
|
selected for collation, and stores the transformed string in the array
|
|

@var{wto}. Up to @var{size} wide characters (including a terminating null
|
|
|
|
character) are stored.
|

The behavior is undefined if the strings @var{wto} and @var{wfrom}

|
|
|
|
|
|
The return value is the length of the entire transformed wide character
|
|
|
|
string. This value is not affected by the value of @var{size}, but if
|
|
|
|
it is greater or equal than @var{size}, it means that the transformed

|
wide character string did not entirely fit in the array @var{wto}. In

this case, only as much of the wide character string as actually fits

@code{wcsxfrm} again with a bigger output array.
|

The transformed wide character string may be longer than the original
|

wide character string, and it may also be shorter.

|
|
|
|
If @var{size} is zero, no characters are stored in @var{to}. In this

case, @code{wcsxfrm} simply returns the number of wide characters that
|
|
|
|
would be the length of the transformed wide character string. This is
|
|
|
|
useful for determining what size the allocated array should be (remember
|
|
|
|
to multiply with @code{sizeof (wchar_t)}). It does not matter what
|
|
|
|
@var{wto} is if @var{size} is zero; @var{wto} may even be a null pointer.

Here is an example of how you can use @code{strxfrm} when
|
|
|
|
you plan to do many comparisons. It does the same thing as the previous
|
|
|
|
example, but much faster, because it has to transform each string only
|
|
|
|
once, no matter how many times it is compared with other strings. Even
|
|
|
|
the time needed to allocate and free storage is much less than the time
|
|
|
|
we save, when there are many strings.

@deftypefun {void *} rawmemchr (const void *@var{block}, int @var{c})
|
|
|
|
Often the @code{memchr} function is used with the knowledge that the
|
|
|
|
byte @var{c} is available in the memory block specified by the
|
|
|
|
parameters. But this means that the @var{size} parameter is not really
|
|
|
|
needed and that the tests performed with it at runtime (to check whether
|
|
|
|
the end of the block is reached) are not needed.
|
|
|
|
|
|
|
|
The @code{rawmemchr} function exists for just this situation which is
|
|
|
|
surprisingly frequent. The interface is similar to @code{memchr} except
|
|
|
|
that the @var{size} parameter is missing. The function will look beyond
|
|
|
|
the end of the block pointed to by @var{block} in case the programmer
|
2001-02-10 18:07:35 +01:00
|
|
|
made an error in assuming that the byte @var{c} is present in the block.
|
2001-02-10 17:37:51 +01:00
|
|
|
In this case the result is unspecified. Otherwise the return value is a
|
|
|
|
pointer to the located byte.
|
|
|
|
|
|
|
|
This function is of special interest when looking for the end of a
|
|
|
|
string. Since all strings are terminated by a null byte a call like
|
|
|
|
|
|
|
|

rawmemchr (str, '\0')

@deftypefun {char *} strchr (const char *@var{string}, int @var{c})
|
|
|
|
The @code{strchr} function finds the first occurrence of the character
|
|
|
|
@var{c} (converted to a @code{char}) in the null-terminated string
|
|
|
|
beginning at @var{string}. The return value is a pointer to the located
|
|
|
|
character, or a null pointer if no match was found.
|
|
|
|
|
|
|
|
For example,
|
|
|
|
@smallexample
|
|
|
|
strchr ("hello, world", 'l')
|
|
|
|
@result{} "llo, world"
|
|
|
|
strchr ("hello, world", '?')
|
|
|
|
@result{} NULL

|
|
|
|
|
|
|
The terminating null character is considered to be part of the string,
|
|
|
|
so you can use this function get a pointer to the end of a string by
|
2012-02-18 00:34:01 +01:00
|
|
|
specifying a null character as the value of the @var{c} argument.
|
|
|
|
|
|
|
|
When @code{strchr} returns a null pointer, it does not let you know
|
|
|
|
the position of the terminating null character it has found. If you
|
|
|
|
need that information, it is better (but less portable) to use
|
|
|
|
@code{strchrnul} than to search for it a second time.

@deftypefun {wchar_t *} wcschr (const wchar_t *@var{wstring}, int @var{wc})

The @code{wcschr} function finds the first occurrence of the wide
|
|
|
|
character @var{wc} in the null-terminated wide character string
|
|
|
|
beginning at @var{wstring}. The return value is a pointer to the

|
located wide character, or a null pointer if no match was found.
|
|
|
|
|
|
|
|
The terminating null character is considered to be part of the wide
|
|

|
character string, so you can use this function get a pointer to the end
|
|
|
|
of a wide character string by specifying a null wude character as the
|
|
|
|
value of the @var{wc} argument. It would be better (but less portable)
|
|
|
|
to use @code{wcschrnul} in this case, though.

One useful, but unusual, use of the @code{strchr}
|
1999-01-27 01:11:04 +01:00
|
|
|
function is when one wants to have a pointer pointing to the NUL byte
|
|
|
|
terminating a string. This is often written in this way:
|
|
|
|
|
|
|
|
@smallexample
|
|
|
|
s += strlen (s);
|
|
|
|
@end smallexample
|
|
|
|
|
|
|
|
@noindent
|
|
|
|
This is almost optimal but the addition operation duplicated a bit of
|
|
|
|
the work already done in the @code{strlen} function. A better solution
|
|
|
|
is this:
|
|
|
|
|
|
|
|
@smallexample
|
|
|
|
s = strchr (s, '\0');
|
|
|
|
@end smallexample
|
|
|
|
|
|
|
|
There is no restriction on the second parameter of @code{strchr} so it
|
|
|
|
could very well also be the NUL character. Those readers thinking very
|
|
|
|
hard about this might now point out that the @code{strchr} function is
|
1999-01-27 10:13:16 +01:00
|
|
|
more expensive than the @code{strlen} function since we have two abort
|
2000-04-28 05:27:50 +02:00
|
|
|
criteria. This is right. But in the GNU C library the implementation of
|
|
|
|
@code{strchr} is optimized in a special way so that @code{strchr}
|
1999-01-27 10:13:16 +01:00
|
|
|
actually is faster.

@deftypefun {char *} strrchr (const char *@var{string}, int @var{c})
|
|

The function @code{strrchr} is like @code{strchr}, except that it searches

backwards from the end of the string @var{string} (instead of forwards
|
|
|
|
from the front).

For example,
|
|
|
|
@smallexample

strrchr ("hello, world", 'l')

@result{} "ld"

@deftypefun {char *} strstr (const char *@var{haystack}, const char *@var{needle})
|
|
|
|
This is like @code{strchr}, except that it searches @var{haystack} for a
|
|
|
|
substring @var{needle} rather than just a single character. It
|
|
|
|
returns a pointer into the string @var{haystack} that is the first
|
|
|
|
character of the substring, or a null pointer if no match was found. If
|
|
|
|
@var{needle} is an empty string, the function returns @var{haystack}.

This is like @code{wcschr}, except that it searches @var{haystack} for a

returns a pointer into the string @var{haystack} that is the first wide

@code{wcswcs} is an deprecated alias for @code{wcsstr}. This is the

This is like @code{strstr}, except that it ignores case in searching for

|
|
the substring. Like @code{strcasecmp}, it is locale dependent how
|
|
|
|
uppercase and lowercase characters are related.

It's fairly common for programs to have a need to do some simple kinds

of lexical analysis and parsing, such as splitting a command string up
|
|

1995-02-18 02:27:10 +01:00
|
|
|
A string can be split into tokens by making a series of calls to the
|
|
|
|
function @code{strtok}.
|
|
|
|
|
|
|
|
The string to be split up is passed as the @var{newstring} argument on
|
|
|
|
the first call only. The @code{strtok} function uses this to set up
|
|
|
|
some internal state information. Subsequent calls to get additional
|
|
|
|
tokens from the same string are indicated by passing a null pointer as
|
|
|
|
the @var{newstring} argument. Calling @code{strtok} with another
|
|
|
|
non-null @var{newstring} argument reinitializes the state information.
|
|
|
|
It is guaranteed that no other library function ever calls @code{strtok}
|
|
|
|
behind your back (which would mess up this internal state information).
|
|
|
|
|
|
|
|
The @var{delimiters} argument is a string that specifies a set of delimiters
|
|
|
|
that may surround the token being extracted. All the initial characters
|
|
|
|
that are members of this set are discarded. The first character that is
|
|
|
|
@emph{not} a member of this set of delimiters marks the beginning of the
|
|
|
|
next token. The end of the token is found by looking for the next
|
|
|
|
character that is a member of the delimiter set. This character in the
|
|
|
|
original string @var{newstring} is overwritten by a null character, and the
|
|
|
|
pointer to the beginning of the token in @var{newstring} is returned.
|
|
|
|
|
|
|
|
On the next call to @code{strtok}, the searching begins at the next
|
|
|
|
character beyond the one that marked the end of the previous token.
|
|
|
|
Note that the set of delimiters @var{delimiters} do not have to be the
|
|
|
|
same on every call in a series of calls to @code{strtok}.
|
|
|
|
|
|
|
|
If the end of the string @var{newstring} is reached, or if the remainder of
|
|
|
|
string consists only of delimiter characters, @code{strtok} returns
|
|
|
|
a null pointer.

@deftypefun {wchar_t *} wcstok (wchar_t *@var{newstring}, const char *@var{delimiters})
|

|

A string can be split into tokens by making a series of calls to the
|
|
|
|
function @code{wcstok}.
|
|
|
|
|
|
|
|
The string to be split up is passed as the @var{newstring} argument on
|
|
|
|
the first call only. The @code{wcstok} function uses this to set up
|
|
|
|
some internal state information. Subsequent calls to get additional
|
|
|
|
tokens from the same wide character string are indicated by passing a
|
|
|

null pointer as the @var{newstring} argument. Calling @code{wcstok}
|
|

with another non-null @var{newstring} argument reinitializes the state

|
information. It is guaranteed that no other library function ever calls

@code{wcstok} behind your back (which would mess up this internal state

information).
|
|
|
|
|
|
|
|
The @var{delimiters} argument is a wide character string that specifies
|
|
|
|
a set of delimiters that may surround the token being extracted. All
|
|
|
|
the initial wide characters that are members of this set are discarded.
|
|
|
|
The first wide character that is @emph{not} a member of this set of
|
|
|
|
delimiters marks the beginning of the next token. The end of the token
|
|
|
|
is found by looking for the next wide character that is a member of the
|
|
|
|
delimiter set. This wide character in the original wide character
|
|
|
|
string @var{newstring} is overwritten by a null wide character, and the
|
|
|
|
pointer to the beginning of the token in @var{newstring} is returned.
|
|
|
|
|
|
|
|
On the next call to @code{wcstok}, the searching begins at the next
|
|
|
|
wide character beyond the one that marked the end of the previous token.
|
|
|
|
Note that the set of delimiters @var{delimiters} do not have to be the
|
|
|
|
same on every call in a series of calls to @code{wcstok}.
|
|
|
|
|
|
|
|
If the end of the wide character string @var{newstring} is reached, or
|
|
|
|
if the remainder of string consists only of delimiter wide characters,
|
|
|
|
@code{wcstok} returns a null pointer.

@strong{Warning:} Since @code{strtok} and @code{wcstok} alter the string
|
|
|
|
they is parsing, you should always copy the string to a temporary buffer
|
|
|
|
before parsing it with @code{strtok}/@code{wcstok} (@pxref{Copying and
|
|
|
|
Concatenation}). If you allow @code{strtok} or @code{wcstok} to modify
|
|
|
|
a string that came from another part of your program, you are asking for
|
|
|
|
trouble; that string might be used for other purposes after
|
|
|
|
@code{strtok} or @code{wcstok} has modified it, and it would not have
|
|
|
|
the expected value.
|
1995-02-18 02:27:10 +01:00
|
|
|
|
|
|
|
The string that you are operating on might even be a constant. Then
|
2001-02-11 02:50:24 +01:00
|
|
|
when @code{strtok} or @code{wcstok} tries to modify it, your program
|
|
|
|
will get a fatal signal for writing in read-only memory. @xref{Program
|
|
|
|
Error Signals}. Even if the operation of @code{strtok} or @code{wcstok}
|
|
|
|
would not require a modification of the string (e.g., if there is
|
|
|
|
exactly one token) the string can (and in the GNU libc case will) be
|
|
|
|
modified.
|
1995-02-18 02:27:10 +01:00
|
|
|
|
|
|
|
This is a special case of a general principle: if a part of a program
|
|
|
|
does not have as its purpose the modification of a certain data
|
|
|
|
structure, then it is error-prone to modify the data structure
|
|
|
|
temporarily.

|
|
|
2001-02-11 02:50:24 +01:00

The functions @code{strtok} and @code{wcstok} are not reentrant.

Just like @code{strtok}, this function splits the string into several
|
|
|
|
tokens which can be accessed by successive calls to @code{strtok_r}.
|
|
|
|
The difference is that the information about the next token is stored in
|
|
|
|
the space pointed to by the third argument, @var{save_ptr}, which is a
|
|
|
|
pointer to a string pointer. Calling @code{strtok_r} with a null
|
|
|
|
pointer for @var{newstring} and leaving @var{save_ptr} between the calls
|
|
|
|
unchanged does the job without hindering reentrancy.

This function is defined in POSIX.1 and can be found on many systems

@deftypefun {char *} strsep (char **@var{string_ptr}, const char *@var{delimiter})
|
1999-07-14 23:05:24 +02:00
|
|
|
This function has a similar functionality as @code{strtok_r} with the
|
|
|
|
@var{newstring} argument replaced by the @var{save_ptr} argument. The
|
|
|
|
initialization of the moving pointer has to be done by the user.
|
|
|
|
Successive calls to @code{strsep} move the pointer along the tokens
|
|
|
|
separated by @var{delimiter}, returning the address of the next token
|
|
|
|
and updating @var{string_ptr} to point to the beginning of the next
|
|
|
|
token.
|
|
|
|
|
|
|
|
One difference between @code{strsep} and @code{strtok_r} is that if the
|
|
|
|
input string contains more than one character from @var{delimiter} in a
|
|
|
|
row @code{strsep} returns an empty string for each pair of characters
|
|
|
|
from @var{delimiter}. This means that a program normally should test
|
|
|
|
for @code{strsep} returning an empty string before processing it.

The function below addresses the perennial programming quandary: ``How do

I take good data in string form and painlessly turn it into garbage?''
|
|
|
|
This is actually a fairly simple task for C programmers who do not use
|
|
|
|
the GNU C library string functions, but for programs based on the GNU C
|
|
|
|
library, the @code{strfry} function is the preferred method for
|
|
|
|
destroying string data.
|
|
|
|
|

The prototype for this function is in @file{string.h}.

@code{strfry} creates a pseudorandom anagram of a string, replacing the

input with the anagram in place. For each position in the string,
|

|
|
@code{strfry} swaps it with a position in the string selected at random
|
|
|
|
(from a uniform distribution). The two positions may be the same.
|
|
|
|
|
|
|

The return value of @code{strfry} is always @var{string}.

The @code{memfrob} function converts an array of data to something
|
|
|
|
unrecognizable and back again. It is not encryption in its usual sense
|
|
|
|
since it is easy for someone to convert the encrypted data back to clear
|
|
|
|
text. The transformation is analogous to Usenet's ``Rot13'' encryption
|
|
|
|
method for obscuring offensive jokes from sensitive eyes and such.
|
|
|
|
Unlike Rot13, @code{memfrob} works on arbitrary binary data, not just

text.

@code{memfrob} transforms (frobnicates) each byte of the data structure
|
|
|
|
at @var{mem}, which is @var{length} bytes long, by bitwise exclusive
|
|
|
|
oring it with binary 00101010. It does the transformation in place and
|
|
|
|
its return value is always @var{mem}.
|
|
|
|
|
|
|
|
Note that @code{memfrob} a second time on the same data structure
|
|
|
|
returns it to its original state.
|
|
|
|
|
|
|
|
This is a good function for hiding information from someone who doesn't
|
|
|
|
want to see it or doesn't want to see it very much. To really prevent
|

|
|
people from retrieving the information, use stronger encryption such as

that described in @xref{Cryptographic Functions}.

this string, and decodes the characters it finds according to the table

This encoding scheme is not standard. There are some other encoding
|
|

|
methods which are much more widely used (UU encoding, MIME encoding).
|
|
|
|
Generally, it is better to use one of these encodings.

|
|
|
|
|
|
|
|
Each argz vector is represented by a pointer to the first element, of
|
|
|
|
type @code{char *}, and a size, of type @code{size_t}, both of which can
|
|
|
|
be initialized to @code{0} to represent an empty argz vector. All argz
|
|
|
|
functions accept either a pointer and a size argument, or pointers to
|
|
|
|
them, if they will be modified.
|
|
|
|
|
|
|
|
The argz functions use @code{malloc}/@code{realloc} to allocate/grow
|
|
|
|
argz vectors, and so any argz vector creating using these functions may
|
|
|
|
be freed by using @code{free}; conversely, any argz function that may
|
|
|
|
grow a string expects that string to have been allocated using
|
|
|
|
@code{malloc} (those argz functions that only examine their arguments or
|
|
|
|
modify them in place will work on any sort of memory).
|
|
|
|
@xref{Unconstrained Allocation}.
|
|
|
|
|
|
|
|
All argz functions that do memory allocation have a return type of
|
|
|
|
@code{error_t}, and return @code{0} for success, and @code{ENOMEM} if an
|
|
|
|
allocation error occurs.
|
|
|
|
|
|
|
|
@pindex argz.h
|
|
|
|
These functions are declared in the standard include file @file{argz.h}.

|
|
|
the elements separated by the character @var{sep}, by replacing each
|
|
|
|
@code{'\0'} inside @var{argz} (except the last one, which terminates the
|
|
|
|
string) with @var{sep}. This is handy for printing @var{argz} in a
|
|
|
|
readable manner.

@deftypefun {char *} argz_next (char *@var{argz}, size_t @var{argz_len}, const char *@var{entry})
|
|
|
|
The @code{argz_next} function provides a convenient way of iterating
|
|
|
|
over the elements in the argz vector @var{argz}. It returns a pointer
|
|
|
|
to the next element in @var{argz} after the element @var{entry}, or
|
|
|
|
@code{0} if there are no elements following @var{entry}. If @var{entry}
|
|
|
|
is @code{0}, the first element of @var{argz} is returned.
|
|
|
|
|
|
|
|
This behavior suggests two styles of iteration:
|
|
|
|
|
|
|
|
@smallexample
|
|
|
|
char *entry = 0;
|
|
|
|
while ((entry = argz_next (@var{argz}, @var{argz_len}, entry)))
|
|
|
|
@var{action};
|
|
|
|
@end smallexample
|
|
|
|
|
|
|
|
(the double parentheses are necessary to make some C compilers shut up
|
|
|
|
about what they consider a questionable @code{while}-test) and:
|
|
|
|
|
|
|
|
@smallexample
|
|
|
|
char *entry;
|
|
|
|
for (entry = @var{argz};
|
|
|
|
entry;
|
|
|
|
entry = argz_next (@var{argz}, @var{argz_len}, entry))
|
|
|
|
@var{action};
|
|
|
|
@end smallexample
|
|
|
|
|
|
|
|
Note that the latter depends on @var{argz} having a value of @code{0} if
|
|
|
|
it is empty (rather than a pointer to an empty block of memory); this
|
|
|
|
invariant is maintained for argz vectors created by the functions here.
|
|
|
|
@end deftypefun
|
|
|
|
|
Update.

@node Envz Functions, , Argz Functions, Argz and Envz Vectors
|

|
|
@subsection Envz Functions
|
|
|
|
|
|
|
|
Envz vectors are just argz vectors with additional constraints on the form
|
|
|
|
of each element; as such, argz functions can also be used on them, where it
|
|
|
|
makes sense.
|
|
|
|
|
|
|
|
Each element in an envz vector is a name-value pair, separated by a @code{'='}
|
|
|
|
character; if multiple @code{'='} characters are present in an element, those
|
|
|
|
after the first are considered part of the value, and treated like all other
|
|
|
|
non-@code{'\0'} characters.
|
|
|
|
|
|
|
|
If @emph{no} @code{'='} characters are present in an element, that element is
|
|
|
|
considered the name of a ``null'' entry, as distinct from an entry with an
|
|
|
|
empty value: @code{envz_get} will return @code{0} if given the name of null
|
|
|
|
entry, whereas an entry with an empty value would result in a value of
|
|
|
|
@code{""}; @code{envz_entry} will still find such entries, however. Null
|
|
|
|
entries can be removed with @code{envz_strip} function.
|
|
|
|
|
|
|
|
As with argz functions, envz functions that may allocate memory (and thus
|
|
|
|
fail) have a return type of @code{error_t}, and return either @code{0} or
|
|
|
|
@code{ENOMEM}.
|
|
|
|
|
|
|
|
@pindex envz.h
|
|
|
|
These functions are declared in the standard include file @file{envz.h}.

|
The @code{envz_merge} function adds each entry in @var{envz2} to @var{envz},

as if with @code{envz_add}, updating @code{*@var{envz}} and
