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 > >
