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 to a capture window.

s

Pointer to a CAPSTATUS structure.

wSize

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

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.

Requirements

**  Windows NT/2000/XP:** Included in Windows NT 3.1 and later.
**  Windows 95/98/Me:** Included in Windows 95 and later.
**  Header:** Declared in Vfw.h.
