" too few arguments to function `call_user_function_ex'"

Hello, Tought this was the best newsgroup to post to, since I'm developing an in-house only additional PHP module. Anyway, I want to call a user function from a function in my module... so I should use call_user_function_ex . Well, I tried the example on the website, and it gives me the error: antrophia.c: In function `zif_antrophia_msgincrease': antrophia.c:147: too few arguments to function `call_user_function_ex' I have pasted the source of that function below... anyone has any idea what I am doing wrong? (and again, I am sorry if this is the wrong group) Thanks in advance. Regards, Leon Mergen --- source PHP_FUNCTION(antrophia_msgincrease) { zval *rtrn; zval **function_name; if((ZEND_NUM_ARGS() != 1) || (zend_get_parameters_ex(1, &function_name) != SUCCESS)) { WRONG_PARAM_COUNT; } if((*function_name)->type != IS_STRING) { zend_error(E_ERROR, "Function requires string argument"); } // Introduce compiler globals (CG) to this function TSRMLS_FETCH(); if(call_user_function_ex(CG(function_table), NULL, *function_name, &rtrn, 0, NULL, 0) != SUCCESS) { zend_error(E_ERROR, "Function call failed"); } zend_printf("We have %i as type<br>", rtrn->type); *return_value = *rtrn; zval_copy_ctor(return_value); zval_ptr_dtor(&rtrn); }
