📦 version 0.12.0, in nixpkgs unstable

💖 COMEDI_CONNECT_ROUTE(3) — Comedi reference, but make it group chat 💖

okay so this is the COMEDI_CONNECT_ROUTE(3) page from the Comedi reference, and it's literally all about connecting a device-global route. bestie, we're in the routing era ✨

🌸 NAME 🌸

comedi_connect_route — connect device-global route

✨ SYNOPSIS ✨

#include <comedilib.h>

int comedi_connect_route(comedi_t * device, unsigned int source,
                         unsigned int destination);

🦋 STATUS 🦋

alpha — yes queen, it's alpha. Still cute, still cooking 💅

💖 DESCRIPTION 💖

This function connects a globally-named route if such is connectible. The way it works is effectively the same as calling comedi_set_routing and comedi_dio_config on the appropriate subdevice. No cap.

There are several routes that are not globally connectable via comedi_connect_route, such as (NI_PFI(i) --> NI_AO_SampleClock), because they must be connected via a trigger argument, such as comedi_cmd->start_arg for NI_AO_StartTrigger. So if that's your route, this function is not the main character for it 😭

The source parameter specifies the source of the signal route, whereas the destination parameter specifies the destination. Possible values for source and destination are driver dependent, but they are generally required to be values that are recognizable globally for a particular device, independent of sub-device. iykyk 🌈

🔥 RETURN VALUE 🔥

0 on success, -1 on error (and errno is set appropriately — EALREADY: route is already connected; EINVAL: route invalid for this device; EBUSY: destination selector used for another route). slay for clarity 💀
