LC_CHANNEL_OTI_PEEK(3)

💖 lc_channel_oti_peek — peek at the OTI header ✨

okay bestie, welcome to lc_channel_oti_peek(3), straight out of the Librecast Programmer's Manual. it's giving "sneak a look, don't touch" and honestly? iconic. 🎀

📚 LIBRARY

Librecast library (liblibrecast, -llibrecast) 🦋

✨ SYNOPSIS ✨

#include <librecast/net.h>

int lc_channel_oti_peek(lc_channel_t *chan, rq_oti_t *oti, rq_scheme_t *scheme);

and like, obvi, you gotta compile and link with -llibrecast or she simply will not run. periodt. 💅

🌸 DESCRIPTION 🌸

so the lc_channel_oti_peek() function peeks at the OTI header — that's the RaptorQ FEC Object Transmission Information header, see RFC 6330 if you wanna go full nerd mode, and you should — sitting inside the next packet of the socket that's bound to channel chan. 👑

then it sets oti and scheme accordingly, like the little matchmaker it is. 🫶

the whole vibe is peek, not consume. she looks, she learns, she does not eat your packet. main character energy fr fr.

🎯 RETURN VALUE 🎯

lc_channel_oti_peek() returns zero on success. slay. 💚

on error, -1 is returned and errno is set to indicate the error. 😭

💀 ERRORS 💀

• EBADMSG — the header is malformed, or T does not match the expected value for chan. like, bestie, that header is not passing the vibe check. 🙈

errno can also be set to any of the errors returned by lc_socket_recv(3) — so if you're confused, go read that one too, iykyk. 🦋
