WM_CAP_SET_CALLBACK_STATUS
The WM_CAP_SET_CALLBACK_STATUS message sets a status callback function in the
application. AVICap calls this procedure whenever the capture window status
changes. You can send this message explicitly or by using the capSetCallbackOnStatus macro.
WM_CAP_SET_CALLBACK_STATUS
wParam = (WPARAM) 0;
lParam = (LPARAM) (LPVOID) (fpProc);
Parameters
fpProc
Address of the status callback function. Specify NULL for this parameter to
disable a previously installed status callback function.
Return Values
Returns TRUE if successful or FALSE if streaming capture or a single-frame
capture sesion is in progress.
Remarks
Applications can optionally set a status callback function. If set, AVICap
calls this procedure in the following situations:
- A capture session is completed.
- A capture driver successfully connected to a capture window.
- An optimal palette is created.
- The number of captured frames is reported.
