💅 mei_cldev_send_vtag_timeout — Kernel API Manual ✨

okay so bestie, welcome to the mei_cldev_send_vtag_timeout(9) page, live from the Kernel API Manual 🫶 this one's all about sending stuff out on a me client device with a virtual tag and a timeout, and yes she writes. main character send function, no cap.

---

🌸 NAME 🌸

mei_cldev_send_vtag_timeout — me device send with vtag and timeout (write)

---

✨ SYNOPSIS ✨

ssize_t mei_cldev_send_vtag_timeout (struct mei_cl_device *cldev , const
u8 *buf , size_t length , u8 vtag , unsigned long timeout );

---

🎀 ARGUMENTS 🎀

bestie there are five of them, here's the whole squad:

• cldev — me client device. the vibe check target, she's the one doing the sending 💖
• buf — buffer to send. literally the payload, the actual stuff going out 📦
• length — buffer length. how much of buf we're talking about, gotta be honest about it
• vtag — virtual tag. the little name tag your message wears so everyone knows who it is 🏷️
• timeout — send timeout in milliseconds, 0 for infinite timeout. so like, patience measured in ms, and 0 means you're willing to wait forever, which is a lot but okay ⏳

---

🌈 RETURN 🌈

• written size in bytes ✅ (slay, it worked)
• < 0 on error 😭 (it did not work, go check your life)
