Memory Leaks

im using c++, so i've overloaded new and delete, new[] and delete[];

using new or new[] increments a certain count variable( one for each ), and delete and delete[] decrements it.

then i have a function that logs the un-deallocated counts, and using atexit( ); i make it the last function called. i have no global objects, so it should be the lst thing executed.

works for me but is plain ugly. bascially whenever i change something and there are un-deallocated pointers i know where to look. wouldnt be much help on an existing project with a huge number of files.

If you're using C/C++ you could use the built in functions.

#define _CRTDBG_MAP_ALLOC
#include
#include

Then in the end:
_CrtDumpMemoryLeaks();

If you're involved in a larger project, you might want to check out payware memory leak detectors though.

If you're running Linux, I definitely recommend Valgrind. It's brilliant.

"built in functions."

are these Microsoft visual c++ built in functions, because my Dev-Cpp doesnt have them and im trying to remain cross platform...

Ops sorry mistake on my part there, not everyone is using msvc =)

Get the Fluid Studios Memory Manager. It will track memory allocations, and give you a list of any blocks that you haven't freed at the end of your program (ie, leaks).

Edit: Also, you may want to skim this thread.
