@node mkstemp
@section @code{mkstemp}
@findex mkstemp
POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/mkstemp.html}
Gnulib module: mkstemp
Portability problems fixed by Gnulib:
@itemize
@item
This function is missing on some platforms:
mingw, MSVC 9.
@item
This function is declared in @code{<unistd.h>} instead of @code{<stdlib.h>}
on some platforms:
MacOS X 10.3.
@item
On some platforms (HP-UX 10.20, SunOS 4.1.4, Solaris 2.5.1), mkstemp has a silly
limit that it can create no more than 26 files from a given template. On
OSF/1 4.0f, it can create only 32 files per process.
@item
On platforms where @code{off_t} is a 32-bit type, @code{mkstemp} may not work
correctly to create files larger than 2 GB. (Cf. @code{AC_SYS_LARGEFILE}.)
@item
On some older platforms, @code{mkstemp} can create a world or group
writable or readable file, if you haven't set the process umask to
077. This is a security risk.
@end itemize
Portability problems not fixed by Gnulib:
@itemize
@end itemize
The gnulib module @code{clean-temp} can create temporary files that will not
be left behind after signals such as SIGINT.
