@node mkstemp
@section @code{mkstemp}
@findex mkstemp
POSIX specification:@* @url{https://pubs.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 14.
@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.
