Thanks for the reply, but libelf doesn?t work for me as I will have to open the file from my library and these give me the offset of the .data and .bss section from the load address. I was wondering if it is possible to directly access this information from a loaded application. I believe this information should be still available in applications address space. Is there any way looking into the applications address space to figure this out as this would be really efficient and would give me the actual address that these sections are mapped to rather than offset from the applications load address.
