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

128 * is SS_NBIO is set. Which means all associations have a seperate send
129 * limit BUT they will NOT ever BLOCK instead you will get an error back
130 * EAGAIN if you try to send to much. If you want the blocking symantics you
131 * set this option at the cost of sharing one socket send buffer size amongst
132 * all associations. Peeled off sockets turn this option off and block. But
133 * since both TCP and peeled off sockets have only one assoc per socket this
134 * is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
135 * model OR peeled off UDP model, but we do allow you to do so. You just use
136 * the normal syscall to toggle SS_NBIO the way you want.

125 * Blocking I/O is enabled on any TCP type socket by default. For the UDP
126 * model if this is turned on then the socket buffer is shared for send
127 * resources amongst all associations. The default for the UDP model is that
128 * is SS_NBIO is set. Which means all associations have a seperate send
129 * limit BUT they will NOT ever BLOCK instead you will get an error back
130 * EAGAIN if you try to send to much. If you want the blocking symantics you
131 * set this option at the cost of sharing one socket send buffer size amongst
132 * all associations. Peeled off sockets turn this option off and block. But
133 * since both TCP and peeled off sockets have only one assoc per socket this
134 * is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
135 * model OR peeled off UDP model, but we do allow you to do so. You just use
136 * the normal syscall to toggle SS_NBIO the way you want.
