yp_err_stringDescriptionyp_err_string() fetches the error message for a given error number. If the error number provided is not a valid error number, a message such as Unknown NIS error code is returned. The error message returned may vary between implementations of NIS. The following table shows the list of messages returned by the glibc implementation of NIS.
ExampleExample 1439. Display all the yp error messages <table border="1"> <?php // Initialize variables $last_errstr = ''; for ($errno = 1; TRUE; ++$errno) { // Find an error message for the given error number $errstr = yp_err_string ($errno); // If the last error message matches the current error message // we have likely gone past the range of valid error numbers if ($last_errstr == $errstr) break; printf ('<tr><td align="right">%d</td><td>%s</td></tr>', $errno, $errstr); $last_errstr = $errstr; } ?> </table>
