DESCRIPTION The explain_fputs_or_die function is used to call the fputs(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_fputs(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_fputs_on_error function is used to call the fputs(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_fputs(3) function, but still returns to the caller. s The s, exactly as to be passed to the fputs(3) system call. fp The fp, exactly as to be passed to the fputs(3) system call.
RETURN VALUE The explain_fputs_or_die function only returns on success, see fputs(3) for more informa‐ tion. On failure, prints an explanation and exits, it does not return. The explain_fputs_on_error function always returns the value return by the wrapped fputs(3) system call.
