	Quick Info

The capSetCallbackOnStatus macro sets a status callback function in the application. AVICap calls this procedure whenever the capture window status changes. You can use this macro or explicitly call the WM_CAP_SET_CALLBACK_STATUS message.

BOOL capSetCallbackOnStatus(

hwnd,
fpProc
);

Parameters
hwnd

Handle of a capture window.

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 session 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.
