Description:

>     This function specifies a callback function to be called during a Vsync wait state.
>     It is used when reading from CD-ROM is carried out in the background or when processing is
>     performed asynchronously with other V periods.
>     Do not try to call too large function or to use an endless loop in a callback.

>     	VOID WaitVsyncCallbackFunc(PVOID pCallbackArguments);

>     pCallbackArguments(input): Pointer to the parameter set at the specification

Parameters:

>     pWaitVsyncCallback(input)
>             This parameter is a pointer to the function in a Vsync wait state.

>     pCallbackArguments(input)
>             This parameter is a pointer to an argument to be passed to the function called at callback.
