io_uring_buf_ring_init - Initialise a buffer ring

#include <liburing.h>
void io_uring_buf_ring_init(struct io_uring_buf_ring *br);

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.


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.
