You probably meant "sizeof(worldState)" rather than "worldState". - You probably have the wrong address: it is very unlikely that a process is storing anything at address 1. _______________________________________________ Do not post admin requests to the list.

And I too hate it. The sole purpose of a _mailing list_ is to communicate using it. Setting the list so that replies goes to the original poster and not to the list defeats that whole purpose. I'm on very many mailing lists, and fortunately this one is one of the few exhibiting this "problem". Sorry for the rant. Before the list embarks on the standard discussion about this, can I point folk towards the standard rejoinder <http://www.unicom.com/pw/reply-to-harmful.html>. I think there are very few people whose firm positions on this question have been changed either by discussion or by this document, and the discussion tends to generate more heat than light. Nonetheless, I thought I'd try to short-circuit the thread a little.

The problem with the original code is the use of VM_REGION_BASIC_INFO rather than VM_REGION_BASIC_INFO_64 (and the corresponding count and structure). _______________________________________________ Do not post admin requests to the list.
