How to track the memory usage in C++

I have a C++ program running under linux. Is it possible to track its memory usage from the code? I am allocating new objects and running out of memory, so I want to keep track of how quickly I am using memory.

Thanks

Valgrinds module massif is exactly what you are looking for.

You could try my experimental heap debugger ;-)

http://www.paulnettle.com/ click "code" then "MMGR" then the graphic that says "CODE" in red letters.

MMGR drops into your project. Include it in any source files where you want comprehensive memory tracking and it does the rest. It really is quite amazing despite the uselessness of his website.

You could overload ::operator new to track the memory usage (normally, everything else goes through this).
