9 Portability problems fixed by Gnulib:
12 This function is missing on some platforms:
15 On platforms where @code{off_t} is a 32-bit type, @code{mkstemp} may not work
16 correctly to create files larger than 2 GB@. (Cf. @code{AC_SYS_LARGEFILE}.)
18 On some older platforms, @code{mkstemp} can create a world or group
19 writable or readable file, if you haven't set the process umask to
20 077. This is a security risk.
23 Portability problems not fixed by Gnulib:
27 The gnulib module @code{clean-temp} can create temporary files that will not
28 be left behind after signals such as SIGINT.
