"It depends on"... Usually you can use some library that will substitute malloc() and operator new calls so that you can track most of memory allocations. Another possibility is to use features offered by a particular operating system, e.g. under Linux you can use /proc interface to access kernel stats on your app, including the amount of memory allocated for the process.
