Hi, I've noticed that building an extension will fail when using macro php_stream_from_zval and there is not return_value variable within the scope.

Well, looks like it's time to install cscope or ctags and use it to see which code actually stands behind a particular macro. ---- #define php_stream_from_zval(xstr, ppzval) ZEND_FETCH_RESOURCE2((xstr), php_stream *, (ppzval), -1, "stream", php_file_le_stream(), php_file_le_pstream())

#define ZEND_FETCH_RESOURCE2(rsrc, rsrc_type, passed_id, default_id, resource_type_name, resource_type1, resource_type2)    \

rsrc = (rsrc_type) zend_fetch_resource(passed_id TSRMLS_CC, default_id, resource_type_name, NULL, 2, resource_type1, resource_type2); \ ZEND_VERIFY_RESOURCE(rsrc);

#define ZEND_VERIFY_RESOURCE(rsrc)      \
   if (!rsrc) {                        \
       RETURN_FALSE;                   \ <------------ nb

} ---- Obviously this macro is not what you need. I guess you need zend_fetch_resource(), which is the function actually used in ZEND_FETCH_RESOURCE2(). -- Wbr, Antony Dovgal
