Member Function Documentation

int Thread::getProcessorUsage

(

Retrieve the percentage of CPU time used by this thread since the last call to this function or object creation.

On multi CPU systems the CPU time is an average.

Returns

percentage of the CPU time used or -1 if this value cannot be computed.
