Tools for memory mapping

[manishgurnaney]

Hi all,
can anyone tell me how to find the memory map of any process? I used the pmap on unix. But my requirement is to check how much memory has been allocated from any library files.
For example suppose i have one a.exe and it load one abc.so file which allocate some memory. so can there be any utility to trace which memory is invoked by which .so file.

Hi ,,

There will a directory created for each process inside /proc ..

you can look into /proc/"proc-id"/map

eg..

-sh-3.2# cat /proc/3318/maps
00173000-0029c000 r-xp 00000000 fd:00 1081738 /lib/libcrypto.so.0.9.8e
0029c000-002af000 rwxp 00129000 fd:00 1081738 /lib/libcrypto.so.0.9.8e
002af000-002b3000 rwxp 002af000 00:00 0
0039e000-0039f000 r-xp 0039e000 00:00 0 [vdso]
005bd000-005c8000 r-xp 00000000 fd:00 1080508 /lib/libgcc_s-4.1.2-20080825.s.1
005c8000-005c9000 rwxp 0000a000 fd:00 1080508 /lib/libgcc_s-4.1.2-20080825.s.1

does that answer your query..?

Hi Narayanan,
I have tried that that gives me Heap Memoray as a separate entry. What i am looking for when i am allocating a memory from heap through a library/So file i should be able to trace it that total how much memory has been allocated from heap for a specific library.
