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 allocates a the descriptor and fills the fields inside the struct. It also makes sure that all fields will follow the CPU endianness. Due to that, the content of the buffer may change.

Returns:

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

void dvb_extension_descriptor_print (struct dvb_v5_fe_parms * parms, const struct dvb_desc * desc)

Prints the content of the extended descriptor.

Parameters:

parms struct dvb_v5_fe_parms pointer to the opened device
desc pointer to struct dvb_desc

void isdb_desc_partial_reception_free (struct dvb_desc * desc)

Frees all data allocated by the ISDB-T partial reception descriptor.

Parameters:

desc pointer to struct dvb_desc to be freed

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

Initializes and parses the ISDB-T partial reception 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 allocates a the descriptor and fills the fields inside the struct. It also makes sure that all fields will follow the CPU endianness. Due to that, the content of the buffer may change.

Returns:

void isdb_desc_partial_reception_print (struct dvb_v5_fe_parms * parms, const struct dvb_desc * desc)

Prints the content of the ISDB-T partial reception descriptor.

Parameters:

parms struct dvb_v5_fe_parms pointer to the opened device

void isdbt_desc_delivery_free (struct dvb_desc * desc)

Frees all data allocated by the ISDB-T terrestrial delivery system descriptor.

Parameters:
