p9_client_flush(9)

💅 p9_client_flush — flush (cancel) a request

Okay bestie, welcome to the glow-up of p9_client_flush, straight out of the Kernel API Manual ✨ this one lives in the 9p corner of the kernel and it's lowkey iconic.

---

🌸 SYNOPSIS 🌸

int p9_client_flush (struct p9_client *c , struct p9_req_t *oldreq );

That's the whole vibe: it returns an int, takes two things, and gets to work. 🫶

---

🎀 ARGUMENTS 🎀

• c — the client state. Your whole client situation, passed in. 💖
• oldreq — the request you want to cancel. The one getting flushed. Bye bestie 👋

---

🦋 DESCRIPTION 🦋

So here's the tea, fr fr: this sends a flush for one particular request, and then it links the flush request to the original request. Two requests, holding hands. 🫶✨

Now the important part — read this carefully, no cap:

The current code only supports a single flush request, even though the protocol itself allows for multiple flush requests to be sent for a single request. So the protocol's out here with main character energy, and the code is like... one (1) flush. That's the limitation. 😭
