ILE C/teraspace capabilities for examining process memory -- C400-L

I'm trying to understand some aspects of the ILE C platform so that I can successfully port an open-source mark-sweep garbage collector.

I'm using teraspace options so that I've got 8 byte pointers and a unix-like memory model.

Essentially the gc wants to be able to scan all global statically allocated and local stack allocated memory plus registers to establish a "root set" for scanning of the heap to determine which blocks of memory are still being referenced.

This leads to some general requirements which I'm unsure are available on this platform:

- Basically, is it possible for a C program to determine storage being used by the running process (and any shared ones dynamically loaded as service programs, a.k.a. "dll's")? - When using setjmp() can it be used to save and restore registers to the stack, such that they can then be examined and coerced into the root set for scanning of the heap? - Is it possible to access the complete data segment(s) and stack of a C program (and procedures within it) on this platform?
