15 The explain_tmpnam_or_die function is used to call the tmpnam(3) system
16 call. On failure an explanation will be printed to stderr, obtained
17 from the explain_tmpnam(3) function, and then the process terminates by
18 calling exit(EXIT_FAILURE).
19
20 The explain_tmpnam_on_error function is used to call the tmpnam(3) sys‐
21 tem call. On failure an explanation will be printed to stderr, obtained
22 from the explain_tmpnam(3) function, but still returns to the caller.

34 the wrapped tmpnam(3) system call.
