ishtp_cl_read_start(9) — Kernel API Manual 🌸

Okay so welcome to the ishtp_cl_read_start(9) page, bestie! This is from the Kernel API Manual and it's literally all about getting ready to read a client message. Let's get into it 💅

---

NAME 🎀

ishtp_cl_read_start — prepare to read a client message

---

SYNOPSIS ✨

int ishtp_cl_read_start (struct ishtp_cl *cl );

---

ARGUMENTS 🫶

• cl — the client device instance, i.e. the actual client thing you're working with

---

DESCRIPTION 💖

So here's the vibe: this function grabs a free buffer from the pool of free read buffers and adds it to the read buffer pool so contents can be added. Then it sends a flow control request to the firmware so the next message can be sent. It's giving prep work and honestly? iconic. 🌈
