pointers in memory

[arvind.nm]

hi ppl,
i am implementing a garbage collector for c++. in order to
trace pointers using the root set, i need some way to distinguish
pointers from data in memory (heap). i.e by analyzing the memory
location pointed by my root set, i have to find if that block furthur
holds a pointer to another block.
can anyone plz help me get a solution to this..

thanx

This is a vast subject. You might want to look through existing C++
garbage collectors to understand their design.
