Re: help request: passing return value

PHP_FUNCTION (or ZEND_FUNCTION - they are the same) includes the function paramters; one of those is: zval *return_value; which already contains an allocated zval (set to NULL). If you want to change this in one of your own functions, you could do something like this: int f1(zval *return_value, ...) { ... change the return_value here ... return SUCCESS; } PHP_FUNCTION(my_func) { if (f1(return_value) == SUCCESS) { /* it worked */ return; } else { /* it didn't work */ php_error(....) } } Also take a look in Zend/zend.h at the definitions for INTERNAL_FUNCTION_PARAMETERS and INTERNAL_FUNCTION_PARAM_PASSTHRU which can be used in you own function declarations to handle the php function paramters. Hope that helps, --Wez.
