SendPortEnable(9)

💖 SendPortEnable(9) — like, the Kernel API Manual entry, bestie 💖

okay so this is SendPortEnable(9) from the Kernel API Manual, and honestly? she's a short one but she's mighty. no cap. let's get into it 🫶

---

✨ NAME ✨

SendPortEnable — literally sends a PortEnable request to an MPT adapter port. that's the whole vibe. 💅

---

🦋 SYNOPSIS 🦋

int SendPortEnable (MPT_ADAPTER *ioc , int portnum , int sleepFlag );

yes the spacing is like that, don't @ me, it's canon ✨

---

🎀 ARGUMENTS 🎀

• ioc — pointer to the MPT_ADAPTER structure. that's your adapter bestie, the main character of this whole situation 👑
• portnum — the port number you wanna enable. which port? this port. 🐚
• sleepFlag — says whether the process is allowed to sleep. like, is napping on the table or is this a no-sleep zone 😴

---

🌸 DESCRIPTION 🌸

so you call SendPortEnable to send a PortEnable and bring the IOC to OPERATIONAL state. that's it, that's the glow-up. it's giving "wake up queen, you're operational now" ✨🔥

returns 0 for success, and non-zero for failure. so like, 0 = slay, anything else = not slay 😭💀
