I have a function where I want to return data in some parameters like fsockopen does. I wasn't sure how to do it, but it looks like fsockopen does it almost right. I think there is one problem with fsockopen: In one place it does: if (arg_count>2) { zval_dtor(*args[2]); ZVAL_LONG(*args[2],errno); } if (arg_count>3) { zval_dtor(*args[3]); ZVAL_STRING(*args[3],strerror(errno),1); } RETURN_FALSE; while in the AF_UNIX case: if(arg_count>2) (*args[2])->value.lval = errno; if(arg_count>3) { (*args[3])->value.str.val = estrdup(strerror(err no)); (*args[3])->value.str.len = strlen((*args[3])->v alue.str.val); } RETURN_FALSE; Stig
