explain_tmpnam_or_die - create a name for a temporary file and report errors
char *explain_tmpnam_or_die(char *pathname);
char *explain_tmpnam_on_error(char *pathname);
The explain_tmpnam_or_die function is used to call the tmpnam(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tmpnam(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_tmpnam_on_error function is used to call the tmpnam(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tmpnam(3) function, but still returns to the caller.
The explain_tmpnam_or_die function only returns on success, see tmpnam(3) for more information. On failure, prints an explanation and exits, it does not return.
The explain_tmpnam_on_error function always returns the value return by the wrapped tmpnam(3) system call.
The explain_tmpnam_or_die function is intended to be used in a fashion similar to the following example:
char *result = explain_tmpnam_or_die(pathname);
