Summary

Signals that the thread has finished reading from the resource.

Pascal

 public procedure EndRead;

Description

EndRead signals that the thread holding read-access to the protected resource has finished reading from the resource. You must call EndRead once for each time you called BeginRead. Even though it is safe to call EndRead while not holding read-access you should not do so. The same is true for calling EndWrite while currently holding read-access. Once all threads have released their read-access locks, currently blocked threads are released. The exact algorithm used to determine which threads to release depends on the Preferred value passed to the constructor.
