Gnulib module: mkstemp

Portability problems fixed by Gnulib:

@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.

The gnulib module @code{clean-temp} can create temporary files that will not
|
|
be left behind after signals such as SIGINT.
