int sm_h223mux_get_datafeed(struct sm_h223mux_datafeed_parms *datafeedp)

Parameters

a structure of the following type:

typedef struct sm_h223mux_datafeed_parms {
	tSMH223muxId h223mux;					/* in */
	enum kSMH223muxOutputType {
		kSMH223muxOutputTypeH245Ctl,
		kSMH223muxOutputTypeAudio,
		kSMH223muxOutputTypeVideo,
		kSMH223muxOutputTypeMux,
	} port;							/* in */
	tSMDatafeedId datafeed;					/* out */
} SM_H223MUX_DATAFEED_PARMS;
