+.SH DESCRIPTION
+.PP
+The
+.BR io_uring_buf_ring_add (3)
+adds a new buffer to the shared buffer ring
+.IR br .
+The buffer address is indicated by
+.I addr
+and is of
+.I len
+bytes of length.
+.I bid
+is the buffer ID, which will be returned in the CQE.
+.I mask
+is the size mask of the ring, available from
+.BR io_uring_buf_ring_mask (3) .
+.I 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
+.BR io_uring_buf_ring_advance (3)
+or
+.BR io_uring_buf_ring_cq_advance (3),
+then
+.I buf_offset
+should be 0. If buffers are provided in a loop before being committed, the
+.I buf_offset
+must be incremented by one for each buffer added.
+
+.SH RETURN VALUE
+None
