pmcraid_allocate_host_rrqs(9)

✨ pmcraid_allocate_host_rrqs(9) ✨

okay bestie, gather round 💖 this one lives in the Kernel API Manual, section 9 — yeah, the kernel section, we're fancy now 💅

---

🌸 NAME 🌸

pmcraid_allocate_host_rrqs — allocate and initialize host RRQ buffers. that's it, that's the whole vibe ✨

---

🦋 SYNOPSIS 🦋

int pmcraid_allocate_host_rrqs (struct pmcraid_instance *pinstance );

like, it takes one thing and gives you back an int. simple. iconic. no cap 🫶

---

🎀 ARGUMENTS 🎀

• pinstance — pointer to the per adapter instance structure. yes, per adapter, like every adapter gets its own little world and this is the VIP pass to it 👑

---

💜 DESCRIPTION 💜

so here's the tea ☕: the return value is 0 and hrrq buffers are allocated. otherwise you get -ENOMEM — that's the "bestie there is literally no memory left" signal 😭

that's the whole function, fr fr. it allocates, it initializes, it returns a number, it moves on with main character energy 🌈
