	Quick Info

The WM_CAP_DRIVER_GET_CAPS message returns the hardware capabilities of the capture driver currently connected to a capture window. You can send this message explicitly or by using the capDriverGetCaps macro.

wParam = (WPARAM) (wSize);

lParam = (LPARAM) (LPVOID) (LPCAPDRIVERCAPS) (psCaps);

Parameters
wSize

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

psCaps

Address of the CAPDRIVERCAPS structure to contain the hardware capabilities.

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

Remarks
The capabilities returned in CAPDRIVERCAPS are constant for a given capture driver. Applications need to retrieve this information once when the capture driver is first connected to a capture window.
