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.
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.
