|
The method succeeded. |
When this method is called, it increments the lock count on the PMP process. For every call to this method, the application should make a corresponding call to IMFPMPServer::UnlockProcess, which decrements the lock count. When the PMP process is ready to exit, it waits for about 3 seconds, or until the lock count reaches zero, before exiting.
