Functions
int	dvb_desc_terrestrial_delivery_init (struct dvb_v5_fe_parms *parms, const uint8_t *buf, struct dvb_desc *desc)
	Initializes and parses the DVB-T terrestrial delivery system descriptor.
void	dvb_desc_terrestrial_delivery_print (struct dvb_v5_fe_parms *parms, const struct dvb_desc *desc)
	Prints the content of the DVB-T terrestrial delivery system descriptor.

Variables

	converts from the descriptor's hierarchy into enum fe_hierarchy, as defined by DVBv5 API.
const unsigned	dvbt_code_rate []
	converts from the descriptor's FEC into enum fe_code_rate, as defined by DVBv5 API.
const uint32_t	dvbt_interval []
	converts from internal representation into enum fe_guard_interval, as defined at DVBv5 API.
const unsigned	dvbt_transmission_mode []
	converts from the descriptor's transmission mode into enum fe_transmit_mode, as defined by DVBv5 API.

Function Documentation

dvb_desc_terrestrial_delivery_init()

int dvb_desc_terrestrial_delivery_init	(	struct dvb_v5_fe_parms *	parms,
		const uint8_t *	buf,
		struct dvb_desc *	desc
	)

Initializes and parses the DVB-T terrestrial delivery system descriptor.

Parameters

parms	struct dvb_v5_fe_parms pointer to the opened device
buf	buffer containing the descriptor's raw data
desc	pointer to struct dvb_desc to be allocated and filled

This function initializes and makes sure that all fields will follow the CPU endianness. Due to that, the content of the buffer may change.

Currently, no memory is allocated internally.

Returns

On success, it returns the size of the allocated struct. A negative value indicates an error.
