COMEDI_GET_VERSION_C(3)

💖 comedi_get_version_code 💖

okay bestie, welcome to the Comedi reference (section 3, manual page COMEDI_GET_VERSION_C(3), if we're being formal about it) and today we're learning about a lil function called comedi_get_version_code. it tells you what version of the Comedi kernel module you're talking to. that's it. that's the whole job. slay, honestly 🎀

---

✨ NAME ✨

comedi_get_version_code — the Comedi version code, and nothing more 💅

---

🦋 SYNOPSIS 🦋

#include <comedilib.h>

int comedi_get_version_code(comedi_t * device);

---

🌸 DESCRIPTION 🌸

so basically, this function returns the Comedi kernel module version code. to even talk to the kernel module, you need a valid Comedi device, and that's the one you pass in through the parameter device. iconic. and if something goes wrong? boom, -1 comes back at you. 😭

now the version code itself is lowkey built different — it's encoded as a bitfield of three 8-bit numbers. for example, 0x00073d is the version code for version 0.7.61. cute, right?? 🍓

ngl though, this function is of limited usefulness. a typical mis-application of this function is to use it to determine if a certain feature is supported. so if your application needs to know of the existence of a particular feature, an existence test function should be written and put in the Comedilib source. that's the move. periodt. 👑

fr fr bestie, don't be out here vibe-checking features with a version number. write the existence test. iykyk.
