capDriverGetCaps macro (vfw.h)

The capDriverGetCaps 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.

Syntax

BOOL capDriverGetCaps(
     hwnd,
     s,
     wSize
);

Parameters

hwnd

Handle to a capture window.

s

Pointer to the CAPDRIVERCAPS structure to contain the hardware capabilities.

wSize

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

Return value
