NAME

       io_uring_buf_ring_init - Initialise a  buffer ring

SYNOPSIS

       #include <liburing.h>

       void io_uring_buf_ring_init(struct io_uring_buf_ring *br);

DESCRIPTION

       io_uring_buf_ring_init(3) initialises br so that it is ready to
       be used. It may be called after io_uring_register_buf_ring(3) but
       must be called before the buffer ring is used in any other way.

RETURN VALUE

       None

NOTES

       Unless manual setup is needed, it's recommended to use
       io_uring_setup_buf_ring(3) as it provides a simpler way to setup
       a provided buffer ring.
