Hello, I would like to send datagrams thru SendTo() instead of Send() in order to bypass copying data to TWSocket's send buffer. When I call SendTo() I have to handle possible errors by myself, but I do not understand exactely whether it's possible that the function returns a positive result smaller than Len.
The online help says: "If no error occurs, sendto returns the total number of bytes sent, which can be less than the number indicated by len." OK, but a little bit later: "For message-oriented sockets, care must be taken not to exceed the maximum packet size of the underlying subnets, which can be obtained by using getsockopt to retrieve the value of socket option SO_MAX_MSG_SIZE. If the data is too long to pass atomically through the underlying protocol, the error WSAEMSGSIZE is returned and no data is transmitted." Does this mean that in UDP either any number of bytes is sent or WSAEMSGSIZE is returned? --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
