mei_cldev_send_timeout(9)

💅 mei_cldev_send_timeout — the "send it and wait" moment

okay so bestie, this page is from the Kernel API Manual, section 9 (that's the kernel API manpage club, very exclusive, very demure). It's about mei_cldev_send_timeout — aka me device send with timeout (write). It's giving "push bytes out to the ME client device, but like, with a clock running". ⏰✨

🎀 SYNOPSIS

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

literally just four things and a return type, no cap. 🫶

---

🌸 ARGUMENTS

• cldev — the me client device. your main character. the device you're sending to. 👑
• buf — buffer to send. this is the actual payload, the lil care package of bytes. 📦
• length — buffer length, aka how many bytes of buf you're actually committing to. don't lie about this one bestie. 😭
• timeout — send timeout in milliseconds. and here's the iconic part: 0 means infinite timeout. so 0 = "we wait forever, we're committed, we're in this relationship". 💀

---

⭐ RETURN

• written size in bytes — the good ending, slay 💖
• < 0 on error — the bad ending, screaming, crying 🧚

okay this list is LONG long, like the group chat when someone says "so anyway". but every single one of these is invited to the party. no one gets left behind. 🌈

icymi: 0 for timeout = infinite. genuinely infinite. plan your little kernel life accordingly. 🙈
