COMEDI_GET_ROUTING(3)

💖 COMEDI_GET_ROUTING 💖

okay hi bestie 🫶 we're in the Comedi reference manual and this page right here is COMEDI_GET_ROUTING(3) — it's short, it's sweet, it's giving "I only do one thing and I do it flawlessly" 💅

✨ NAME ✨

comedi_get_routing — get routing for an output 🎀

✨ SYNOPSIS ✨

#include <comedilib.h>

int comedi_get_routing(comedi_t * device, unsigned int subdevice,
                       unsigned int channel, unsigned int * routing);

✨ STATUS ✨

alpha 🌱 — yeah she's still in her alpha era, handle with love

✨ DESCRIPTION ✨

So like. This function queries the routing for an output — the routing that got set over there by comedi_set_routing ✨. Whatever routing is currently configured gets written into *routing, okay? And the possible values + what routing each one corresponds to? That's driver-dependant, so no, I cannot tell you the list, it literally depends on your driver, bestie 😭

⚠️ Important vibe check: this function is only useable on subdevices that provide support for the INSN_CONFIG_GET_ROUTING configuration instruction. If your subdevice isn't serving that instruction, it is not going to work. Periodt.

✨ RETURN VALUE ✨

• 0 on success 🎉
• -1 on error 💀
