I fully agree. JNI is crap. However, let face it, our internals APIs is really not good. Yes, there were/are on going efforts for small parts but overall it is a pain to achieve simple things. -- Pierre @pierrejoye | http://www.libgd.org -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
