COMEDI_DIO_BITFIELD(3)

πŸ’– comedi_dio_bitfield(3) πŸ’–

okay bestie so this page lives in the Comedi reference manual (that's the manual name, iykyk) and it's all about comedi_dio_bitfield β€” she reads and writes a whole bunch of digital channels at once. multiple. not just one. she's an overachiever, we love her for it. ✨


✨ NAME ✨

comedi_dio_bitfield β€” read/write multiple digital channels πŸŽ€


✨ SYNOPSIS ✨

#include <comedilib.h>

int comedi_dio_bitfield(comedi_t * device, unsigned int subdevice,
                        unsigned int write_mask, unsigned int * bits);

like. that's the whole thing. four args. she's lowkey elegant.


πŸ’€ STATUS πŸ’€

deprecated

yes bestie. deprecated. we're gonna get into it below. not me telling you about the retirement of a legend 😭


🌸 DESCRIPTION 🌸

okay so first things first, and I need you to hear me on this one: this function is deprecated. like, officially. it's giving "still works but pls move on." πŸ™ˆ

so like β€” use comedi_dio_bitfield2 instead. that's the glow-up version.

and here's the tea: comedi_dio_bitfield is literally equivalent to using comedi_dio_bitfield2 with base_channel set to 0. that's it. that's the whole relationship. same energy, just with base_channel = 0, periodt. πŸ‘‘
