capGetStatus

The capGetStatus macro retrieves the status of the capture window. You can use this macro or explicitly call the WM_CAP_GET_STATUS message.

BOOL capGetStatus(

hwnd,
s,
wSize
);

Parameters
hwnd

Handle of a capture window.

wSize

Size, in bytes, of the structure referenced by s.

Address of a CAPSTATUS structure.

Return Values
Returns TRUE if successful or FALSE if the capture window is not connected to a capture driver.

Remarks
The CAPSTATUS structure contains the current state of the capture window. Since this state is dynamic and changes in response to various messages, the application should initialize this structure after sending the capDlgVideoFormat macro and whenever it needs to enable menu items or determine the actual state of the window.
