ibmvmc_send_close(9)

🎀 NAME 🎀

okay bestie, welcome to ibmvmc_send_close(9) from the Kernel API Manual — this page is literally called Interface Close, and it’s the goodbye/terminate moment for a management application to hypervisor connection. 💅

---

✨ SYNOPSIS ✨

int ibmvmc_send_close (struct ibmvmc_hmc *hmc );

---

🫶 ARGUMENTS 🫶

• hmc — a pointer to the ibmvmc_hmc struct. that’s the whole argument, bestie 🫶

---

💖 DESCRIPTION 💖

A management partition sends this command when it’s terminating a management application to hypervisor connection. no cap, that’s the job. 💖

When this command goes out, the management partition has already quiesced all I/O operations to all buffers associated with this management application connection, and it has freed any storage for these buffers. so by the time this command appears, those buffers are donezo and their storage is already released. periodt. ✨

🔥 RETURN 🔥

• 0 — Success 🔥
• Non-zero — Failure 💀
