💖 COMEDI_RANGE_IS_CHAN 💖

okay bestie, welcome to the Comedi reference section of the manual, page COMEDI_RANGE_IS_CHAN(3) — yes we are literally in section 3, the library-call girlies, periodt. grab a strawberry 🍓 and let's get into it.

✨ NAME ✨

comedi_range_is_chan_specific — range info depends on channel 👀

🌸 SYNOPSIS 🌸

#include <comedilib.h>

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

like, that's the whole vibe. two args, one int back. simple. iconic. 🎀

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — this function is basically asking "does every channel get to have its own lil range situation, or are they all matching?"

If each channel of the subdevice you specified could have different range information, this function returns 1. slay, they're individuals 💅

Otherwise, this function returns 0. they're all twinning, no cap.

And if something goes wrong? On error, this function returns -1. 😭 not the error arc.
