How I find memory leak?

[Daniele C. <dca...@in...>]

I am searching a memory leak in my application.In TQ3Status E3Exit(void) 
function I read:

Q3Memory_DumpRecording( "Quesa-leaks.txt", "Q3Exit" );

Can it useful for me? How I can activate? I don't find documentaion 
about it. Have you some suggest for me?
