Function Documentation

void atsc_table_eit_free (struct atsc_table_eit * table)

Frees all data allocated by the ATSC EIT table parser.

Parameters:

table pointer to struct atsc_table_eit to be freed

ssize_t atsc_table_eit_init (struct dvb_v5_fe_parms * parms, const uint8_t * buf, ssize_t buflen, struct atsc_table_eit ** table)

Initializes and parses ATSC EIT table.

Parameters:

parms struct dvb_v5_fe_parms pointer to the opened device
buf buffer containing the EIT raw data
buflen length of the buffer
table pointer to struct atsc_table_eit to be allocated and filled

This function allocates an ATSC EIT table 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 atsc_table_eit_print (struct dvb_v5_fe_parms * parms, struct atsc_table_eit * table)

Prints the content of the ATSC EIT table.

Parameters:

parms struct dvb_v5_fe_parms pointer to the opened device
table pointer to struct atsc_table_eit

void atsc_table_mgt_free (struct atsc_table_mgt * table)

Frees all data allocated by the MGT table parser.

Parameters:

table pointer to struct atsc_table_mgt to be freed

ssize_t atsc_table_mgt_init (struct dvb_v5_fe_parms * parms, const uint8_t * buf, ssize_t buflen, struct atsc_table_mgt ** table)

Initializes and parses MGT table.

Parameters:

parms struct dvb_v5_fe_parms pointer to the opened device
buf buffer containing the MGT raw data
buflen length of the buffer
table pointer to struct atsc_table_mgt to be allocated and filled

This function allocates an ATSC MGT table 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 atsc_table_mgt_print (struct dvb_v5_fe_parms * parms, struct atsc_table_mgt * table)

Prints the content of the MGT table.

Parameters:

parms struct dvb_v5_fe_parms pointer to the opened device
table pointer to struct atsc_table_mgt

void atsc_table_vct_free (struct atsc_table_vct * table)

Frees all data allocated by the VCT table parser.

Parameters:

table pointer to struct atsc_table_vct to be freed

ssize_t atsc_table_vct_init (struct dvb_v5_fe_parms * parms, const uint8_t * buf, ssize_t buflen, struct atsc_table_vct ** table)

Initializes and parses VCT table.

Parameters:

parms struct dvb_v5_fe_parms pointer to the opened device
buf buffer containing the VCT raw data

1 dvb_table_nit_descriptor_handler(
2                 &parms->p, dvb_scan_handler->nit,
