问题 I have the following code in C: (void)fscanf(fp, "%*d %*d %d %d %d\n",&z, &e, &a); I cast the call to void as the return value of fscanf is irrelevant for me. But I get the following warning when compiling: warning: ignoring return value of ‘fscanf’, declared with attribute warn_unused_result [-Wunused-result] (void)fscanf(fp, "%*d %*d %d %d %d\n",&z, &e, &a); Shouldn't the '(void)' have taken that warning out? 回答1: That's a nice warning, since ignoring the return value of fscanf() could lead

Can I turn off this option, and log just my own exceptions? 回答1: You can always place an error reporting condition in your index.php like: error_reporting(E_ALL ^ E_DEPRECATED); For more info: http://php.net/manual/en/function.error-reporting.php Or you can edit error.php in your joomla directory, and public static function raiseNotice($code, $msg, $info = null) { //
