💖 NAME 💖

comedi_set_routing — pick which signal shows up on an output, bestie 💅

✨ SYNOPSIS ✨

#include <comedilib.h>

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

🌸 STATUS 🌸

alpha — yeah she's still in her soft-launch era 🦋

🎀 DESCRIPTION 🎀

Okay so picture this: you have a multiplexed output channel, right, and it's the kind of channel that can spit out a whole bunch of different signals — think NI's RTSI and PFI lines, that vibe 🌈. This function is the one that configures it.

The routing parameter is the ✨main character✨ here: it selects which signal should be routed to show up on the output channel you picked. And heads up — it's driver-dependant, so no cap, every driver gets to have its own opinions about it 🙈.

Wanna know what routing is currently set? Just ask comedi_get_routing, she'll tell you 💬.

⚠️ Real talk though: this function is only useable on subdevices that provide support for the INSN_CONFIG_SET_ROUTING configuration instruction. No support, no routing, periodt 💀.

⭐ RETURN VALUE ⭐

  • 0 on success 🎉
  • -1 on error 😭
