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

Handle of a
capture window.

Size, in
bytes, of the structure referenced by s.
psCaps
Address of
the CAPDRIVERCAPS
structure to contain the hardware capabilities.
Return Values
