104 * Implementation of sendmsg() for WIN32
106 * We are using a contrived definition of msghdr which actually uses
107 * an array of ::_WSABUF structures instead of ::iovec . This allows
108 * us to call WSASend directly using the given ::msghdr instead of
109 * having to allocate another array of ::_WSABUF and copying data for
114 * - msg->msg_name is ignored. So is msg->control.
115 * - WSASend() only supports ::MSG_DONTROUTE, ::MSG_OOB and
118 * @param[in] s The socket to use.
119 * @param[in] msg The message
120 * @param[in] flags Flags. A combination of ::MSG_DONTROUTE,
121 * ::MSG_OOB and ::MSG_PARTIAL
123 * @return The number of bytes sent, on success. Or -1 on error.
