Great explanation, thank you.

Just one thing that makes me curious... beforehand, some words on the situation. I've developed a highly specific, thread-safe allocator for a CAD-Kernel not using the OS-malloc utility. Originally designed on Win32, this allocator is using the Virtual* functions for allocation. As a post further down stated, those functions are highly straightforward. On my way to LINUX one question pains me: do I have to care for sbrk() at all or may I exclusively use the mmap() functions (and by-the-way gain POSIX conformance)? More precisely, by giving a start address to mmap(), can I force mmap() to go below the sbrk() threshold? The latter figure somewhat supposes that this is possible...

Further information is gratefully appreciated.

Christian.
