The WM_CAP_GET_STATUS message retrieves the status of the capture window. You can send this message explicitly or by using the capGetStatus macro.
WM_CAP_GET_STATUS wParam = (WPARAM) (wSize); lParam = (LPARAM) (LPVOID) (LPCAPSTATUS) (s);
Size, in bytes, of the structure referenced bys.
Pointer to a CAPSTATUS structure.
Returns TRUE if successful or FALSE if the capture window is not connected to a capture driver.
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 WM_CAP_DLG_VIDEOFORMAT message (or using the capDlgVideoFormat macro) and whenever it needs to enable menu items or determine the actual state of the window.
