/*
@defvr Extension HOST_CHARSET
This macro indicates the basic character set and encoding used by the
host: more precisely, the encoding used for character constants in
preprocessor @samp{#if} statements (the C "execution character set").
It is defined by @file{safe-ctype.h}, and will be an integer constant
with one of the following values:
@ftable @code
@item HOST_CHARSET_UNKNOWN
The host character set is unknown - that is, not one of the next two
possibilities.
@item HOST_CHARSET_ASCII
The host character set is ASCII.
@item HOST_CHARSET_EBCDIC
The host character set is some variant of EBCDIC. (Only one of the
nineteen EBCDIC varying characters is tested; exercise caution.)
@end ftable
@end defvr
@deffn Extension ISALPHA (@var{c})
@deffnx Extension ISALNUM (@var{c})
@deffnx Extension ISBLANK (@var{c})
@deffnx Extension ISCNTRL (@var{c})
@deffnx Extension ISDIGIT (@var{c})
@deffnx Extension ISGRAPH (@var{c})
@deffnx Extension ISLOWER (@var{c})
@deffnx Extension ISPRINT (@var{c})
@deffnx Extension ISPUNCT (@var{c})
@deffnx Extension ISSPACE (@var{c})
@deffnx Extension ISUPPER (@var{c})
@deffnx Extension ISXDIGIT (@var{c})
These twelve macros are defined by @file{safe-ctype.h}. Each has the
same meaning as the corresponding macro (with name in lowercase)
defined by the standard header @file{ctype.h}. For example,
@code{ISALPHA} returns true for alphabetic characters and false for
others. However, there are two differences between these macros and
those provided by @file{ctype.h}:
@itemize @bullet
@item These macros are guaranteed to have well-defined behavior for all
values representable by @code{signed char} and @code{unsigned char}, and
for @code{EOF}.
@item These macros ignore the current locale; they are true for these
fixed sets of characters:
@multitable {@code{XDIGIT}} {yada yada yada yada yada yada yada yada}
@item @code{ALPHA} @tab @kbd{A-Za-z}
@item @code{ALNUM} @tab @kbd{A-Za-z0-9}
@item @code{BLANK} @tab @kbd{space tab}
@item @code{CNTRL} @tab @code{!PRINT}
@item @code{DIGIT} @tab @kbd{0-9}
@item @code{GRAPH} @tab @code{ALNUM || PUNCT}
@item @code{LOWER} @tab @kbd{a-z}
@item @code{PRINT} @tab @code{GRAPH ||} @kbd{space}
@item @code{PUNCT} @tab @kbd{`~!@@#$%^&*()_-=+[@{]@}\|;:'",<.>/?}
@item @code{SPACE} @tab @kbd{space tab \n \r \f \v}
@item @code{UPPER} @tab @kbd{A-Z}
@item @code{XDIGIT} @tab @kbd{0-9A-Fa-f}
@end multitable
Note that, if the host character set is ASCII or a superset thereof,
all these macros will return false for all values of @code{char} outside
the range of 7-bit ASCII. In particular, both ISPRINT and ISCNTRL return
false for characters with numeric values from 128 to 255.
@end itemize
@end deffn
@deffn Extension ISIDNUM (@var{c})
@deffnx Extension ISIDST (@var{c})
@deffnx Extension IS_VSPACE (@var{c})
@deffnx Extension IS_NVSPACE (@var{c})
@deffnx Extension IS_SPACE_OR_NUL (@var{c})
@deffnx Extension IS_ISOBASIC (@var{c})
These six macros are defined by @file{safe-ctype.h} and provide
additional character classes which are useful when doing lexical
analysis of C or similar languages. They are true for the following
sets of characters:
@multitable {@code{SPACE_OR_NUL}} {yada yada yada yada yada yada yada yada}
@item @code{IDNUM} @tab @kbd{A-Za-z0-9_}
@item @code{IDST} @tab @kbd{A-Za-z_}
@item @code{VSPACE} @tab @kbd{\r \n}
@item @code{NVSPACE} @tab @kbd{space tab \f \v \0}
@item @code{SPACE_OR_NUL} @tab @code{VSPACE || NVSPACE}
@item @code{ISOBASIC} @tab @code{VSPACE || NVSPACE || PRINT}
@end multitable
@end deffn
