The explain_puts_or_die function is used to call the puts(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_puts(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

The explain_puts_on_error function is used to call the puts(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_puts(3) function, but still returns to the caller.

The explain_puts_on_error function always returns the value return by the wrapped puts(3) system call.
