COMEDI_MAXDATA_IS_CH(3)

💖 COMEDI_MAXDATA_IS_CH(3) 💖

okay bestie, welcome to the Comedi reference page for comedi_maxdata_is_chan_specific, the silliest-named little function with the most serious job 🦋

---

✨ NAME ✨

comedi_maxdata_is_chan_specific — maximum sample depends on channel

---

✨ SYNOPSIS ✨

#include <comedilib.h>

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

---

✨ DESCRIPTION ✨

so like. here's the tea ☕

if every single channel of the subdevice you passed in might have a different maximum sample value — like, no two channels are guaranteed to agree on their max — then this function hits you with a 1. yes queen, they're channel-specific 💅

otherwise? it returns 0. one size fits all, boring but valid 🎀

and if something goes wrong? it returns -1. that's the "uh oh bestie" signal, no cap 😭
