I'm not sure what is the point of the question, but the previous patch doesn't omit resetting the Win32-event in that case. In the same way with other implements of the same function, it resets the trigger that woke up the process since the trigger is no longer needed even if we are not waiting on it. If we call WaitLatch(OrSocket) that waits on the latch, it immediately returns because the latch is set. If we called ResetLatch before the next call to WaitLatch(), it correctly waits on a trigger to be pulled. regards. -- Kyotaro Horiguchi NTT Open Source Software Center
