How to Find the address where Heap begins from within the program?

saurabh.azad · 03-06-2007, 01:33 AM

We need to check whether the memory falls within the heap range before processing it. For this i need to knw the starting address of the heap. Heap end can be knwn from __curbrk i guess. We do not have access to the code where malloc was first called to allocate the memory. Any help??

Try to debug the application with ddd, if it's possible. Next thing you could try is to disassemble the application. A way to do that is with SoftIce (but i'm not sure if it works under Linux) or LDasm (which 100% runs under Linux).

sbrk(0) gives the end of allocated memory
size <filename> gives the initial size of program segments.
