Wait Debugging (Compact 2013)
3/26/2014
DirectShow provides facilities for wait debugging. These facilities build on the Win32 HANDLE-based wait facilities, but you can expand them to debug specific wait conditions.
In the debug build, you can update the global current time-out with calls to DbgSetWaitTimeout.
Updating the current time-out does not affect debug wait calls that are already waiting.
If this is a debug build and a value named TIMEOUT exists in the registry under the HKEY_LOCAL_MACHINE\SOFTWARE\Debug\GLOBAL key, the TIMEOUT value is used as the initial current time-out.
TIMEOUT must be a REG_DWORD value and is measured in milliseconds. If not, the initial time-out defaults to INFINITE.
Call the following functions to perform debuggable waiting.
