Hello, What is the best way (from lisp) to to monitor the total memory allocation during runtime of a foreign library that is doing calls malloc/free ? what about memory size in lisp as well ? I want to make sure I am not incurring memory leaks by making calls into my foreign library...
Thanks, Kevin

I think you'll have to use the same techniques you would use in plain C. See for example: http://stackoverflow.com/questions/1906228. However, your Lisp's memory management might interfere. For instance, Valgrind and SBCL don't get along at all.
You might have better luck with tools that only instrument malloc()/free() if your implementation doesn't use malloc() to allocate Lisp memory, e.g. SBCL.

There's CL:ROOM, and most Lisps have memory profilers. (I'm not aware of any such profilers including foreign memory usage, unfortunately.)
You might get better informed answers if you ask this question on your Lisp's mailing list.
HTH.
