COMEDI_GET_N_RANGES(3)

✨ COMEDI_GET_N_RANGES ✨

okay bestie, welcome to comedi_get_n_ranges(3) — it's a Comedi reference page, it's short, it's sweet, and it's literally just "how many ranges does this channel have" 💅

---

🌸 NAME 🌸

comedi_get_n_ranges — number of ranges of channel

---

🎀 SYNOPSIS 🎀

#include <comedilib.h>

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

---

💖 DESCRIPTION 💖

so the function comedi_get_n_ranges returns the number of ranges of the channel channel belonging to the subdevice subdevice of the comedi device device. that's it. that's the whole job. 🦋

and no cap — this function returns -1 on error. so if you get a negative number back, that's not a vibe, that's a problem. 😭
