COMEDI_SET_GLOBAL_OO(3)

✨ COMEDI_SET_GLOBAL_OO 💖

okay bestie, welcome to the comedi_set_global_oo manual page, straight outta the Comedi reference 🎀 this is the one about out-of-range behavior, and yes it's exactly as dramatic as it sounds. sit down, grab a strawberry 🍓, and let's get into it.

💅 NAME

comedi_set_global_oor_behavior — out-of-range behavior ✨

---

🌸 SYNOPSIS

#include <comedilib.h>

enum comedi_oor_behavior
                                                               comedi_set_global_oor_behavior(enum comedi_oor_behavior behavior);

(yes the wrapping is like that, no I did not do it, that's just how it is 💀)

---

🦋 DESCRIPTION

so basically this function changes the Comedilib out-of-range behavior. it's giving ~global vibes~ because it's like, the setting for the whole library, not just one thing. 🌈

rn it affects how comedi_to_phys behaves when it's converting endpoint sample values, which is a fancy way of saying sample values equal to 0 or maxdata. that's the edge, bestie. the boundary. the main character moments. 👑

and here's the tea on what those two behaviors do:

• if the out-of-range behavior is set to COMEDI_OOR_NAN, endpoint values get converted to NAN 😭 (yes, Not A Number, it's giving mystery)
• if the out-of-range behavior is set to COMEDI_OOR_NUMBER, the endpoint values get converted similarly to other values — chill, normal, no drama, everyone's treated the same 🫶

periodt. that's the whole vibe.

---

⭐ RETURN VALUE

the previous out-of-range behavior is returned ✨ so you get the old setting handed back to you like a lil souvenir of what came before. iconic.
