COMEDI_SET_MAX_BUFFE(3)

πŸ’… COMEDI_SET_MAX_BUFFE(3) πŸ’…

okay bestie so this one's from the Comedi reference manual, section 3 (the library calls, iykyk), and it's all about telling your subdevice how big its streaming buffer is allowed to get. let's get into it 🫢


✨ NAME ✨

comedi_set_max_buffer_size β€” sets the streaming maximum buffer size of a subdevice


πŸ¦‹ SYNOPSIS πŸ¦‹

#include <comedilib.h>

int comedi_set_max_buffer_size(comedi_t * device,
                               unsigned int subdevice,
                               unsigned int max_size);

🌸 DESCRIPTION 🌸

so comedi_set_max_buffer_size changes the maximum allowable size (in bytes) of the streaming buffer for the subdevice you point at with device and subdevice. it's giving "caps off, but make it bytes" πŸŽ€

and the tea β˜• β€” changing the maximum buffer size requires the user to have appropriate privileges. so like, no sneaking in and resizing stuff without permission, that's not very main character of you πŸ™ˆ


πŸ’– RETURN VALUE πŸ’–

  • on success, comedi_set_max_buffer_size returns the new maximum buffer size in bytes. slay ✨
  • on failure, -1 is returned. 😭
