capStatusCallback

The capStatusCallback function is the status callback function used with video capture. The capStatusCallback status callback function is a placeholder for the application-supplied function name.

  HWND hWnd,  
  int nID,    
  LPCSTR lpsz 
);
 

Parameters

hWnd

Handle of the capture window associated with the callback function.

nID

Message identification number.

lpsz

Address of a textual description of the returned status.

Remarks

During capture operations, the first message sent to the callback function is always IDS_CAP_BEGIN and the last is always IDS_CAP_END. A message identifier of zero indicates a new operation is starting and the callback function should clear the current status.
