COMEDI_DATA_READ_N(3)

💖 COMEDI_DATA_READ_N(3) 💖

okay bestie, welcome to the Comedi reference, section 3, and today's main character is comedi_data_read_n 🎀 this is the page for reading a whole bunch of samples, not just one, so buckle up 🦋

---

✨ NAME ✨

comedi_data_read_n — read multiple samples from channel 👑

---

✨ SYNOPSIS ✨

#include <comedilib.h>

int comedi_data_read_n(comedi_t * device, unsigned int subdevice,
                        unsigned int channel, unsigned int range,
                        unsigned int aref, lsampl_t * data,
                        unsigned int n);

---

✨ DESCRIPTION ✨

so basically it's giving comedi_data_read energy, except instead of one lil sample it reads n samples straight into the array data. slay. 💅

but here's the tea bestie, and I need you to hear me on this one: the precise timing of the samples is not hardware controlled. no cap. the hardware is NOT driving the clock on these, so don't come for me expecting perfectly spaced samples 💀
