Greetings, I'm interested in using mmap() with MAP_STACK. After writing a couple of test programs and looking at vm_map_insert() and vm_map_stack(), it appears that vm_map_stack() behaves as if MAP_FIXED were set. Why is this? I would like to allocate stack space without having to search for available blocks. Is there any harm in modifying vm_map_stack() to search for a free block, a la vm_map_insert()? I've not delved extensively into the kernel, and am asking before I tinker in new territory. :-) TIA, Eddy --------------------------------------------------------------------------- Brotsman & Dreger, Inc.
