Anyway, I am leading to this: it is wrong, to check errno-value anywhere, except right after the call, which sets errno The proper solution would be, to have a pointer to some structure passed to the callchain above, and explicitly store error-code/string in virtual_file_ex() -- Alexey Zakhlestin http://blog.milkfarmsoft.com/ -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
