CCmdQueue::GetDueCommand
Microsoft DirectShow 9.0 |
CCmdQueue::GetDueCommand
The GetDueCommand method retrieves a pointer to the next command that is due.
Syntax
virtual HRESULT GetDueCommand( CDeferredCommand **ppCmd, long msTimeout );
Parameters
ppCmd
Address of a pointer to the deferred command.
msTimeout
Amount of time to wait before carrying out the time-out.
Return Value
Returns E_ABORT if a time-out occurs. Returns S_OK if successful; otherwise, returns an error. Returns an object that has been incremented using IUnknown::AddRef.
Remarks
This member function blocks until a pending command is due. The member function blocks for the amount of time, in milliseconds, specified in the msTimeout parameter. Stream-time commands become due only between the CCmdQueue::Run and CCmdQueue::EndRun member functions. The command remains queued until run or canceled.
Requirements
** Header:** Declared in Winutil.h; include Streams.h.
** Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
