💅 host1x_channel_get_index(9) 💅

okay so this is from the Kernel API Manual and honestly it's giving "small function, big responsibilities" energy ✨

---

🌸 NAME 🌸

host1x_channel_get_index — attempting to grab a channel reference by index, bestie 🎀

---

🦋 SYNOPSIS 🦋

struct host1x_channel * host1x_channel_get_index (struct host1x *host ,
       unsigned int index );

like, yes, the whitespace before that comma is exactly how it's written, i don't make the rules 💀

---

🙈 ARGUMENTS 🙈

• host — the Host1x device object, aka the main character of this whole situation 👑
• index — the index of the channel you're asking about 🔢

---

✨ DESCRIPTION ✨

okay so here's the vibe check: if the channel number index is currently allocated, the function bumps up its refcount and hands you back a pointer to it 🫶

otherwise? it returns NULL. that's it. no drama, no cap 💅
