Data Structures

struct dvb_extension_descriptor
Structure containing the extended descriptors.
struct dvb_ext_descriptor
Structure that describes the parser functions for the extended descriptors.


typedef int(* dvb_desc_ext_init_func) (struct dvb_v5_fe_parms *parms, const uint8_t *buf, struct dvb_extension_descriptor *ext, void *desc)
Function prototype for the extended descriptors parsing init code.
typedef void(* dvb_desc_ext_print_func) (struct dvb_v5_fe_parms *parms, const struct dvb_extension_descriptor *ext, const void *desc)
Function prototype for the extended descriptors parsing print code.
typedef void(* dvb_desc_ext_free_func) (const void *desc)
Function prototype for the extended descriptors parsing free code.
