COMEDI_GET_MAX_BUFFE(3)

✨ COMEDI_GET_MAX_BUFFE(3) β€” the Comedi reference glow-up ✨

okay bestie, sit down, hydrate, because you're about to learn comedi_get_max_buffer_size and it's genuinely not that deep, I promise πŸ’– this one lives in the Comedi reference manual (section 3, the library-call girly), so let's get into it πŸŽ€


🌸 NAME 🌸

comedi_get_max_buffer_size β€” maximum streaming buffer size, that's the whole vibe πŸ¦‹


✨ SYNOPSIS ✨

#include <comedilib.h>

int comedi_get_max_buffer_size(comedi_t * device,
                               unsigned int subdevice);

πŸ’… DESCRIPTION πŸ’…

okay so comedi_get_max_buffer_size hands you back the maximum allowable size (in bytes) of the streaming buffer for the subdevice you point at with device and subdevice. that's it. that's the function. it's giving very "one job, does it well" πŸ‘‘

ngl if you actually want to change that maximum buffer size, you can't do it here, bestie β€” that's a comedi_set_max_buffer_size situation, or you can go through the comedi_config program instead. and heads up: changing it requires appropriate privileges, so don't come for me when it yells at you πŸ™ˆ


🌈 RETURN VALUE 🌈

  • on the slay path: you get the maximum allowable size (in bytes) of the streaming buffer πŸ’–
  • on the not-slay path: you get -1 πŸ’€
