Re: [flame] [new proto allocation]
Date: 02/17/97

best method to use and that's what I'm using is every time you add a room
or what ever, create a new proto with size of the original one + another
entry and while that is done of course it is locked, then
memmove((void) new_proto, (void) old_proto, sizeof(old_proto));
works very nicely for me =)
