You have to vm_deallocate() it, otherwise it'll leak. > And if I wanted to pass a buffer in and reuse it, I should use > vm_allocate() instead of malloc()? You can use malloc, you'll then have to use free on it *and* vm_deallocate the value set by the RPC if it did change the pointer. That's clearer to just use vm_deallocate in both case. See how it's done in various codeplaces, you'll find tests such as if (buf != alloc_buf) vm_deallocate(alloc_buf); Samuel
