On failure an explanation will be printed to stderr, obtained from the explain_printf(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_printf_on_error function is used to call the printf(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_printf(3) function, but still returns to the caller. format The format, exactly as to be passed to the printf(3) system call.
RETURN VALUE The explain_printf_or_die function only returns on success, see printf(3) for more infor‐ mation. On failure, prints an explanation and exits, it does not return. The explain_printf_on_error function always returns the value return by the wrapped printf(3) system call.
