C ++ unit test memory leak

I just resolved a memory leak in my application, and now I want to write unit test so that this does not happen again.

I am looking for a way to determine the memory usage of the current application (working set) before and after some functions.

For instance:

long mem_used= GetMemUsed(); 
/* Do some work */
/* clean up */

if( mem_used != GetMemUsed() ) {
    Error( "Memory leek" ); 
}

I found many ways to detect memory usage throughout the system, but none of them are used only for the current application.

Suggestions, links, code snippets?

Boost.Test will automatically inform you at the end of the test run if any of your modules checks for a memory leak.
