💖 intel_guc_ct_init(9) 💖

okay bestie, so this is a page from the Kernel API Manual and it's literally all about intel_guc_ct_init — the little function that gets buffer-based communication ready to go. she's giving setup era, she's giving pre-game. 🎀

✨ NAME ✨

intel_guc_ct_init — Init buffer-based communication

like yes, that's the whole vibe: init. the beginning. the "let's get this party started" of buffer-based communication. 🦋

---

🌸 SYNOPSIS 🌸

int intel_guc_ct_init (struct intel_guc_ct *ct );

she takes exactly one thing and she returns an int. simple, iconic, no notes. 💅

---

🧚 ARGUMENTS 🧚

• ct — pointer to CT struct. that's it. that's the whole argument. you hand her the CT struct pointer and she does her thing, periodt. 🫶

---

👑 DESCRIPTION 👑

Allocate memory required for buffer-based communication.

that's the tea fr fr — this is the function whose entire job is to go get the memory that buffer-based communication needs. no cap, that's literally it. she allocates, she provides, she moves on. 💀✨

---

🌈 RETURN 🌈

• 0 on success 🎉
• a negative errno code on failure 😭

so like, zero means she ate and left no crumbs, and anything negative means something went sideways and you get an errno code telling you how sideways. check your return values, bestie. 🙈
