✨ COMEDI_CANCEL(3) ✨

okay bestie, this is a page from the Comedi reference manual — section 3, the library-calls girlies 💅 — and it's literally just one function. One. Little. Function. And it's the stop button. Let's get into it 🫶

🌸 NAME 🌸

comedi_cancel — stop streaming input/output in progress

like. it cancels. it's the ✨cancel✨ of comedi. no cap.

🎀 SYNOPSIS 🎀

#include <comedilib.h>

int comedi_cancel(comedi_t * device, unsigned int subdevice);

look at her. two args. returns an int. she's so simple and she knows it 👑

💖 DESCRIPTION 💖

so comedi_cancel is the function you call when you wanna stop a command that's already running. Specifically: a command that was started earlier by comedi_command and is still in progress on the subdevice — you know, the one you point at with your device and subdevice parameters 🦋

that's it. that's the whole function. it's the "aight imma head out" of streaming I/O 😭

⭐ RETURN VALUE ⭐

  • 0 — that's a slay, it worked, success, periodt 💅
  • -1 — bestie it failed, something went sideways 😭
