CAPDRIVERCAPS structure
The CAPDRIVERCAPS structure defines the capabilities of the capture driver.
An application should use the WM_CAP_DRIVER_GET_CAPS message or capDriverGetCaps macro to place a copy of the driver capabilities in a CAPDRIVERCAPS structure whenever the application connects a capture window to a capture driver.
Syntax
