ureq_select(9)

💖 ureq_select(9) 💖

okay so welcome to the Kernel API Manual, bestie — this is the ureq_select(9) page, and it’s literally about selecting the next request in a context. No cap, it’s giving “small function, important job” energy. 💅

---

🎀 NAME 🎀

ureq_select — select the next request in a context. periodt. ✨

✨ SYNOPSIS ✨

struct qcomtee_ureq * ureq_select (struct qcomtee_context_data *ctxdata
, size_t ubuf_size , int num_params );

🫶 ARGUMENTS 🫶

• ctxdata — context data for a context to pop a request from. That’s the context we’re working with, iykyk.
• ubuf_size — size of the available buffer for UBUF parameters. That’s the buffer size number, fr fr.
• num_params — number of entries for the TEE parameter array. That’s the count of array entries, no cap.

🦋 DESCRIPTION 🦋

So here’s the vibe: it checks if num_params is large enough to fit the next request arguments. It also checks if ubuf_size is large enough to fit IB buffer arguments. That’s the whole size-check moment, and it’s highkey important. ✨

🔒 CONTEXT 🔒

The caller should hold qcomtee_context_data->reqs_lock.

bestie, this is the lock situation: the caller should hold qcomtee_context_data->reqs_lock. Do not skip the lock vibe check. 🔐

💫 RETURN 💫

On success, it returns a request; on failure, it returns NULL and ERR_PTR. So yeah — success gets you a request, failure gets you NULL and ERR_PTR. 😭
