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

155 * EAGAIN if you try to send too much. If you want the blocking semantics you
156 * set this option at the cost of sharing one socket send buffer size amongst
157 * all associations. Peeled off sockets turn this option off and block. But
158 * since both TCP and peeled off sockets have only one assoc per socket this
159 * is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
160 * model OR peeled off UDP model, but we do allow you to do so. You just use
