The capDriverGetVersion macro returns the version information of the capture driver connected to a capture window. You can use this macro or explicitly send the WM_CAP_DRIVER_GET_VERSION message.

);

szVer
Pointer to an application-defined buffer used to return the version information as a null-terminated string.
wSize
