10.46.39 mkostemp ¶

POSIX specification:
https://pubs.opengroup.org/onlinepubs/9799919799/functions/mkostemp.html

Documentation:
man mkostemp

Gnulib module: mkostemp

Portability problems fixed by Gnulib:

• This function is missing on many non-glibc platforms: glibc 2.6, Mac OS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, Solaris 11.4, Cygwin 1.7.5, mingw, MSVC 14, Android 5.1.
• This function is declared in <unistd.h> instead of <stdlib.h> on some platforms: macOS 14.
• On platforms where off_t is a 32-bit type, mkostemp may not work correctly to create files larger than 2 GB. (Cf. AC_SYS_LARGEFILE.)

Portability problems not fixed by Gnulib:

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