💖 COMEDI_TRIGGER 💖

okay bestie, welcome to the Comedi reference — this one's COMEDI_TRIGGER(3) and she's lowkey a legend, but also… retired. we'll get to that. 🫶

✨ NAME ✨

comedi_trigger — do streaming input/output. deprecated, babe. 💀

🌸 SYNOPSIS 🌸

#include <comedilib.h>

int comedi_trigger(comedi_t * device, comedi_trig * trig);

like. that's the whole vibe. two params. very demure. 🎀

🚨 STATUS 🚨

deprecated

literally the whole section is just that word. the status is deprecated. no notes. she said it herself. 😭

👑 DESCRIPTION 👑

so here's the tea: comedi_trigger tells Comedi to go do the command that's described by the trigger structure — and that structure is the one your trig pointer is pointing at. 🪄

and the return value?? it depends on the particular trigger being issued. it's giving mystery, it's giving "we'll see", it's giving main character energy with no fixed ending. 🙈

but if there's an error? -1 gets returned. classic. simple. consistent. love that for us. 💅
