NAME

       io_uring_buf_ring_add - add buffers to a shared buffer ring

SYNOPSIS

       #include <liburing.h>

       int io_uring_buf_ring_add(struct io_uring_buf_ring *br,
                                 void *addr,
                                 unsigned int len,
                                 unsigned short bid,
                                 int mask,
                                 int buf_offset);

DESCRIPTION

       The  io_uring_buf_ring_add(3)  adds a new buffer to the shared buffer ring br.  The buffer
       address is indicated by addr and is of len bytes of length.  bid is the buffer  ID,  which
       will  be  returned  in  the  CQE.   mask  is  the  size  mask  of the ring, available from
       io_uring_buf_ring_mask(3).  buf_offset is the offset to insert at from the  current  tail.
       If   just   one   buffer   is   provided   before   the   ring   tail  is  committed  with
       io_uring_buf_ring_advance(3) or io_uring_buf_ring_cq_advance(3), then buf_offset should be
       0.  If  buffers  are  provided  in  a  loop before being committed, the buf_offset must be
       incremented by one for each buffer added.

RETURN VALUE

       None
