    Stack Manipulation

    I've read some about creating garbage collectors (for other languages)
    in C, and conservative garbage collectors sometimes manipulate the
    program stack to look for pointers.

    How would I do it?

    Where can I find functions to manipulate/find things out about the
    program stack?

    Also in a similar vein, how can I dump all the processor registers to
    the stack?

    I realize this probably isn't cross-platform AT ALL. I would just
    appreciate a few pointers on how to do this, especially on Linux/x86
    set ups.

    Thanks

              Don't worry about it. That was written by one of our resident trolls.
              Please ignore him. Really.
