capDriverGetVersion macro

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.

Syntax


BOOL capDriverGetVersion(
   hwnd,
   szVer,
   wSize
);

Parameters

hwnd

Handle to a capture window.

szVer

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

wSize

Size, in bytes, of the application-defined buffer referenced by szVer.

Return value

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