explain_tmpfile_or_die(3) Library Functions Manual explain_tmpfile_or_die(3) NAME explain_tmpfile_or_die - create a temporary file and report errors SYNOPSIS #include <libexplain/tmpfile.h> FILE *explain_tmpfile_or_die(void); FILE *explain_tmpfile_on_error(void); DESCRIPTION The explain_tmpfile_or_die function is used to call the tmpfile(3) sys- tem call. On failure an explanation will be printed to stderr, obtained from the explain_tmpfile(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_tmpfile_on_error function is used to call the tmpfile(3) system call. On failure an explanation will be printed to stderr, ob- tained from the explain_tmpfile(3) function, but still returns to the caller. RETURN VALUE The explain_tmpfile_or_die function only returns on success, see tmp- file(3) for more information. On failure, prints an explanation and ex- its, it does not return. The explain_tmpfile_on_error function always returns the value return by the wrapped tmpfile(3) system call.
