int GetCaDescriptors	(	int	Source,
		int	Transponder,
		int	ServiceId,
		const int *	CaSystemIds,
		int	BufSize,
		uchar *	Data,
		bool &	StreamFlag
	)

Gets all CA descriptors for a given channel. Copies all available CA descriptors for the given Source, Transponder and ServiceId into the provided buffer at Data (at most BufSize bytes). Only those CA descriptors are copied that match one of the given CA system IDs.

Returns:

Returns the number of bytes copied into Data (0 if no CA descriptors are available), or -1 if BufSize was too small to hold all CA descriptors. The return value in StreamFlag tells whether these CA descriptors are to be used for the individual streams.
