149 * Blocking I/O is enabled on any TCP type socket by default. For the UDP

154 * EAGAIN if you try to send too much. If you want the blocking semantics you
155 * set this option at the cost of sharing one socket send buffer size amongst

157 * since both TCP and peeled off sockets have only one assoc per socket this
158 * is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
