Hi: the first MACRO is a tricky way to put a number of ZEND_NUM_BUCKETS zend_mm_buckects into a fixed length array. and yes, my site might be blocked by chinese GFW, but you can try this: https://wiki.php.net/internals/zend_mm plz see the red part of the first picture.. thanks -- Laruence Xinchen Hui http://www.laruence.com/ -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
