✨ comedi_close_from(9) ✨

Welcome to the Kernel API Manual, bestie — we're literally in kernel-land rn. 🧚 This page is about closing a COMEDI device from the kernel, with loop checks. No cap.

🌸 NAME 🌸

comedi_close_from — Close a COMEDI device from the kernel with loop checks. 💅

✨ SYNOPSIS ✨

int comedi_close_from (struct comedi_device *dev , int from );

🎀 ARGUMENTS 🎀

• dev — COMEDI device. The main-character device struct, periodt. 👑
• from — Device number it was opened from (if in range). Keep that parenthetical, bestie — it matters. 🫶

💅 DESCRIPTION 💅

Closes a COMEDI device previously opened by comedi_open_from. So it's the close-side buddy, the "we're done here" moment. 🦋

If from is in range, it should be match the one used by comedi_open_from. Yep, that's the wording — keep the same from value, iykyk. ⭐

🫶 RETURN 🫶

0 — that's the whole return value. Nothing extra, no plot twist. 💖
