Function Documentation
| 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.
