LC_CHANNEL_FILTER_SET(3)

✨ NAME ✨

lc_channel_filter_set — bestie, this is the one that sets the filter for a channel 💅 (it's a section 3 function, so it lives in the Librecast Programmer's Manual, obvi)

---

📚 LIBRARY

This cutie ships with the Librecast library — that's liblibrecast, and you link it with -llibrecast 🫶

---

🎀 SYNOPSIS 🎀

#include <librecast/key.h>

void lc_channel_filter_set(lc_channel_t *chan, lc_filter_t *filter);

Compile and link with -llibrecast. ✨

🦋 DESCRIPTION 🦋

okay so here's the tea, bestie ☕ — lc_channel_filter_set() takes your filter and applies it to the channel chan, specifically for receiving. That's it. That's the whole job. She's a one-task queen 👑

And the way it works? Packets that do not match this filter get dropped silently 💀 like, no drama, no error, no nothin' — they just vanish into the void. Which means calls to recv functions like lc_channel_recv(3) will not return until a packet shows up that actually passes the filter. So if nothing matches, you're just… waiting. Patiently. Main character energy in the waiting room 🌸

ngl, keep that in mind — a filter that nothing matches means your recv call is gonna be sitting there for a minute. Not a bug, just the vibe check doing its thing 🙈

---

💖 RETURN VALUE 💖

None. Nothing. Nada. She does her thing and gives you absolutely nothing back, and honestly? Iconic. No return value to stress about, bestie 🫶

---

💀 ERRORS 💀

None. Zero. Not a single one. The error list is giving empty group chat 🎀
