#8115 — Number of times a function is called

For debugging purposes,

I need to check that my program calls functions xxx_alloc() and xxx_free() 
from a (dynamic or static) library the same number of times (every 
allocation is followed by exactly one deallocation).

How to do this on Linux?

If you're looking to detect/identify memory leaks, I'd suggest looking
at Valgrind.

If these functions do allocations you might find valgrind useful.

If you want to count the actual calls (without instrumenting the source)
you can use gprof(1) and the -pg flag to gcc.

You might get more advice in comp.unix.programmer
