explain_tmpfile_or_die - create a temporary file and report errors
The explain_tmpfile_or_die function is used to call the tmpfile(3) system 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, obtained from the explain_tmpfile(3) function, but still returns to the caller.
The explain_tmpfile_or_die function only returns on success, see tmpfile(3) for more information. On failure, prints an explanation and exits, it does not return.
The explain_tmpfile_on_error function always returns the value return by the wrapped tmpfile(3) system call.
The explain_tmpfile_or_die function is intended to be used in a fashion similar to the following example:
FILE *result = explain_tmpfile_or_die();
