void TGo4ThreadManager::Launch ( )

This Method has to be called to create the startup threads and to turn on the application control timer. Usually this is done at the end of the user's threadmanager constructor. The idea is that no thread should be started unless the user initializations are done; therefore, its up to the user to define when to Launch.

Bool_t TGo4ThreadManager::UnBlockApp ( Int_t mode = 0 )

Wakes up the control timer waiting for his condition; parameter mode specifies whether timer will block again at next turn (mode=0), timer will block when all threads are up (mode=1), or timer will not block again unless the next Block call, i.e. applicationrun flag is reset (mode=2)
