Problem with returning a resource.

Hello, I am in the process of writting an extension to php, but I have run into a problem when I try to return a resource back to the php program, php then segfaults. I have included below the code that I am triing to get to work, in the hopes that someone can point and laugh at me while they show me the mistake that I made. Thanks in advance. Gordon. PHP_FUNCTION(rbo_open) { char *account = NULL; char *object = NULL; char *username = NULL; char *password = NULL; int argc = ZEND_NUM_ARGS(); int account_len; int object_len; int username_len; int password_len; zval *rbo = NULL; RBOObj *rboobj = NULL; if (argc == 4) { if (zend_parse_parameters(argc TSRMLS_CC, "ssss", &account, &account_len, &object, &object_len, &username, &username_len, &password, &password_len) == FAILURE) return; } else if (argc == 2) { if (zend_parse_parameters(argc TSRMLS_CC, "ss", &account, &account_len, &object, &object_len) == FAILURE) return; } else { php_error(E_WARNING, "rbo_open: wrong number of arguments"); RETURN_FALSE; } zend_printf("%s %s\n",account, object); if (rboobj = rbo_open(account, object, username, password)) { zend_printf("rbo_open(%s,%s) complete\n",account, object); ZEND_REGISTER_RESOURCE(rbo, rboobj, rbo_rsrc_id); zend_printf("%ld\n", *rbo); zend_printf("rbo_open(%s,%s) register resource\n",account, object); RETURN_RESOURCE(rbo); } else { zend_printf("rbo_open(%s,%s) failed\n",account, object); RETURN_FALSE; } } /* }}} */ -- Gordon Heydon <gordon@heydon.com.au>
