Normally file sizes are maintained automatically. A file begins with a
|
||||
size of @math{0} and is automatically extended when data is written
|
||||
past its end. It is also possible to empty a file completely in an
|
||||
@code{open} or @code{fopen} call.
|
||||
|
||||
However, sometimes it is neccessary to @emph{reduce} the size of a file.
|
||||
This can be done with the @code{truncate} and @code{ftruncate} functions.
|
||||
They were introduced in BSD Unix. @code{ftruncate} was later added to
|
||||
POSIX.1.
|
||||
|
||||
Some systems allow you to extend a file (creating holes) with these
|
||||
functions. This is useful when using memory-mapped I/O
|
||||
(@pxref{Memory-mapped I/O}), where files are not automatically extended.
|
||||
However it is not portable but must be implemented if @code{mmap} allows
|
||||
mapping of files (i.e., @code{_POSIX_MAPPED_FILES} is defined).
|
||||
|
||||
Using these functions on anything other than a regular file gives
|
||||
@emph{undefined} results. On many systems, such a call will appear to
|
||||
succeed, without actually accomplishing anything.
|
||||
|
||||
@deftypefun int truncate (const char *@var{filename}, off_t @var{length})
|
||||
|
||||
The @code{truncate} function changes the size of @var{filename} to
|
||||
@var{length}. If @var{length} is shorter than the previous length, data at
|
||||
the end will be lost.
|
||||
|
||||
If @var{length} is longer, holes will be added to the end. However, some
|
||||
systems do not support this feature and will leave the file unchanged.
|
||||
|
||||
The return value is @math{0} for success, or @math{-1} for an error. In
|
||||
addition to the usual file name errors, the following errors may occur:
|
||||
|
||||
@table @code
|
||||
|
||||
@item EACCES
|
||||
The file is a directory or not writable.
|
||||
|
||||
@item EINVAL
|
||||
@var{length} is negative.
|
||||
|
||||
@item EFBIG
|
||||
The operation would extend the file beyond the limits of the operating system.
|
||||
|
||||
@item EIO
|
||||
A hardware I/O error occured.
|
||||
|
||||
@item EPERM
|
||||
The file is "append-only" or "immutable".
|
||||
|
||||
@item EINTR
|
||||
The operation was interrupted by a signal.
|
||||
|
||||
@end table
|
||||
|
||||
@end deftypefun
|
||||
|
||||
@deftypefun int ftruncate (int @var{fd}, off_t @var{length})
|
||||
|
||||
This is like @code{truncate}, but it works on a file descriptor @var{fd}.
|
||||
|
||||
@code{ftruncate} is especially useful in combination with @code{mmap}.
|
||||
Since the mapped region must have a fixed size one cannot enlarge the
|
||||
file by writing something beyond the last mapped page. Instead one has
|
||||
to enlarge the file itself and then remap the file with the new size.
|
||||
The example below shows how this works.
|
||||
|
||||
The return value is @math{0} for success, or @math{-1} for an error. The
|
||||
following errors may occur:
|
||||
|
||||
@table @code
|
||||
|
||||
@item EBADF
|
||||
@var{fd} does not correspond to an open file.
|
||||
|
||||
@item EACCES
|
||||
@var{fd} is a directory or not open for write.
|
||||
|
||||
@item EINVAL
|
||||
@var{length} is negative.
|
||||
|
||||
@item EFBIG
|
||||
The operation would extend the file beyond the limits of the operating system.
|
||||
@c or the open() call -- with the not-yet-discussed feature of opening
|
||||
@c files with extra-large offsets.
|
||||
|
||||
@item EIO
|
||||
A hardware I/O error occured.
|
||||
|
||||
@item EPERM
|
||||
The file is "append-only" or "immutable".
|
||||
|
||||
@item EINTR
|
||||
The operation was interrupted by a signal.
|
||||
|
||||
@c ENOENT is also possible on Linux --- however it only occurs if the file
|
||||
@c descriptor has a `file' structure but no `inode' structure. I'm not
|
||||
@c sure how such an fd could be created. Perhaps it's a bug.
|
||||
|
||||
@end table
|
||||
|
||||
@end deftypefun

As announced here is a little example how to use @code{ftruncate} in
|
||||
combination with @code{mmap}:
|
||||
|
||||
@smallexample
|
||||
int fd;
|
||||
void *start;
|
||||
size_t len;
|
||||
|
||||
int
|
||||
add (off_t at, void *block, size_t size)
|
||||
@{
|
||||
if (at + size > len)
|
||||
@{
|
||||
/* Resize the file and remap. */
|
||||
size_t ps = sysconf (_SC_PAGESIZE);
|
||||
size_t ns = (at + size + ps - 1) & ~(ps - 1);
|
||||
void *np;
|
||||
if (ftruncate (fd, ns) < 0)
|
||||
return -1;
|
||||
np = mmap (NULL, ns, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0);
|
||||
if (np == MAP_FAILED)
|
||||
return -1;
|
||||
start = np;
|
||||
len = ns;
|
||||
@}
|
||||
memcpy ((char *) start + at, block, size);
|
||||
return 0;
|
||||
@}
|
||||
@end smallexample
|
||||
|
||||
The function @code{add} allows to add at arbitrary positions in the file
|
||||
given blocks of memory. If the current size of the file is too small it
|
||||
is extended. Please note the it is extended in multiples of a pagesize.
|
||||
This is a requirement of @code{mmap}. The program has to track the real
|
||||
size and once the program finished to work a final @code{ftruncate} call
|
||||
should set the real size of the file.
