When running RThread::GetCpuTime() on an n-gage, the return value is KErrNotSupported. The docs say the method exists from Symbian 6.1. The method works in the emulator.

Is there any other way of determining the cpu usage of a thread or process?

How about other Symbian devices? 6600?

If someone has a 6600 and wants to try, my small app (a very simple version of the unix "top" utility) can be found here:

If all cpu and time usage shows up as "0", GetCpuTime() does not work...
