Member Function Documentation

◆ GetAvailableThreads()

ASPOSECPP_SHARED_API void System::Threading::ThreadPoolImpl::GetAvailableThreads ( int &  wt,
int &  cpt 
)

Gets number of available threads.

Parameters
wtReference to variable to store number of awailable worker threads.
cptReference to variable to store number of awailable IO threads.
