DESC_EXTENSION.H(3)

👑 NAME

okay so bestie, welcome to lib/include/libdvbv5/desc_extension.h — she's the header that Provides the descriptors for the extension descriptor. That's the whole assignment, and she ate. 💅

---

✨ SYNOPSIS ✨

#include <libdvbv5/descriptors.h>

🎀 Data Structures

• struct dvb_extension_descriptor — Structure containing the extended descriptors. the main character honestly.
• struct dvb_ext_descriptor — Structure that describes the parser functions for the extended descriptors. she's the backstage crew making it all happen 🫶

🦋 Typedefs

• dvb_desc_ext_init_func — Function prototype for the extended descriptors parsing init code. it's giving "here's how you start the party":

typedef int(* dvb_desc_ext_init_func) (struct dvb_v5_fe_parms *parms,
    const uint8_t *buf, struct dvb_extension_descriptor *ext, void
    *desc)

• dvb_desc_ext_print_func — Function prototype for the extended descriptors parsing print code. say it loud, say it proud:

typedef void(* dvb_desc_ext_print_func) (struct dvb_v5_fe_parms *parms,
    const struct dvb_extension_descriptor *ext, const void *desc)

• dvb_desc_ext_free_func — Function prototype for the extended descriptors parsing free code. cleanup era, we love to see it:

typedef void(* dvb_desc_ext_free_func) (const void *desc)

🌈 Enumerations

• enum extension_descriptors — List containing all extended descriptors used by Digital TV MPEG-TS as defined at ETSI EN 300 468 V1.11.1. every single one of these girls, in order, no skips:
  1. image_icon_descriptor
  2. cpcm_delivery_signalling_descriptor
  3. CP_descriptor
  4. CP_identifier_descriptor
  5. T2_delivery_system_descriptor
  6. SH_delivery_system_descriptor
  7. supplementary_audio_descriptor
  8. network_change_notify_descriptor
  9. message_descriptor
  10. target_region_descriptor
  11. target_region_name_descriptor
  12. service_relocated_descriptor

💜 Functions

• int dvb_extension_descriptor_init (struct dvb_v5_fe_parms *parms, const uint8_t *buf, struct dvb_desc *desc) — Initializes and parses the extended descriptor. wake her up and read her mind 🔮
• void dvb_extension_descriptor_print (struct dvb_v5_fe_parms *parms, const struct dvb_desc *desc) — Prints the content of the extended descriptor. spill the tea, queen ☕
• void dvb_extension_descriptor_free (struct dvb_desc *desc) — Frees all data allocated by the extended descriptor. release her, no holding on ✨

🌸 Detailed Description 🌸

Provides the descriptors for the extension descriptor.

The extension descriptor is used to extend the 8-bit namespace of the descriptor_tag field. lowkey genius, highkey necessary. 🧚

okay that's the whole page, periodt. this one's libdvbv5, Version 1.32.0, and it lives at lib/includ...extension.h(3). go forth and parse those extended descriptors, you gorgeous nerd 🦋💅🔥
