from the explain_mkstemp(3) function, and then the process terminates
by calling exit(EXIT_FAILURE).
The explain_mkstemp_on_error function is used to call the mkstemp(3)
system call. On failure an explanation will be printed to stderr,
obtained from the explain_mkstemp(3) function, but still returns to the
caller.
- template

RETURN VALUE

mkstemp(3) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_mkstemp_on_error function always returns the value return
by the wrapped mkstemp(3) system call.
