160 * user socket options: BSD implementation specific
163 * Blocking I/O is enabled on any TCP type socket by default. For the UDP
164 * model if this is turned on then the socket buffer is shared for send
165 * resources amongst all associations. The default for the UDP model is that
166 * is SS_NBIO is set. Which means all associations have a separate send
167 * limit BUT they will NOT ever BLOCK instead you will get an error back
168 * EAGAIN if you try to send too much. If you want the blocking semantics you
169 * set this option at the cost of sharing one socket send buffer size amongst
170 * all associations. Peeled off sockets turn this option off and block. But
171 * since both TCP and peeled off sockets have only one assoc per socket this
172 * is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
173 * model OR peeled off UDP model, but we do allow you to do so. You just use
174 * the normal syscall to toggle SS_NBIO the way you want.
176 * Blocking I/O is controlled by the SS_NBIO flag on the socket state so_state
