A way to know the memory use ?

How can I know the memory resources of my system ?
Total, used, etc.
Thanks

There is no Qt API to determine that, so you need to implement platform specific calls for that.

And .... for windows systems ?
Thanks

For both physical and virtual memory: GlobalMemoryStatusEx

Thanks Stampede.
And... Is it possible to know the memory use of my application (made with QT, of course).
Thanks again
