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 .SH SEE ALSO .BR io_uring_register_buf_ring (3), .BR io_uring_buf_ring_mask (3), .BR io_uring_buf_ring_advance (3), .BR io_uring_buf_ring_cq_advance (3)
