okay so we're doing a comedi_disarm_channel(3) deep dive and honestly? it's a short one but it's important. sit down, grab a strawberry 🍓, let's go.

✨ NAME ✨

comedi_disarm_channel — disarm a subdevice channel 🎀

🦋 SYNOPSIS 🦋

#include <comedilib.h>

int comedi_disarm_channel(comedi_t * device, unsigned int subdevice,
                          unsigned int channel);

⚠️ STATUS ⚠️

alpha. yes bestie, alpha — it's giving experimental, it's giving "handle with care", it's giving lowercase-greek-letter energy. 🫶

🌸 DESCRIPTION 🌸

Okay so what does this actually do? It disarms a specified channel of a subdevice. Like, it chills it out. It stops it. If your channel is a counter that's out here counting away, this function can literally make it stop counting. main character moment for the off switch 💅

Here's the catch tho: this function is only useable on subdevices that provide support for the INSN_CONFIG_DISARM configuration instruction. No support for that instruction? No arm to disarm. That's the vibe check right there.

And then there's the plot twist 🙈 — some subdevices treat this as an instruction to disarm the whole subdevice and just ignore the specified channel entirely. Like, bestie, I asked for one channel and you gave me the entire subdevice?? For those subdevices, comedi_disarm is normally called instead.

🎯 RETURN VALUE 🎯

  • 0 — success, we ate, periodt 👑
  • -1 — error, it's giving 💀
