int km=socketDescriptor.flush();
cerr << "cannot send data ";
close(socketDescriptor);
exit(1);

Hi all,
HOw can I flush the socket.
When I first read the subject line, my brain read it as, "How to flush a
toilet." I guess I've been sitting here at my desk too long! :-)

There's no such thing as a "socket" in the C++ language. You must be
referring to a resource that's provided by your operating system. This
newsgroup is for the discussion of the C++ language. Try asking in a
newsgroup or a mailing list that's more appropriate for your operating
system.
Generally, the BSD socket API does not define a mechanism to verify
succesful transmission of data over a socket. Eventually, if the receiver
fails to ACK, the socket will be marked as broken, and writes will fail, but
this will not happen until quite some time has elapsed.

sorry it was supposed to be,
if (send(socketDescriptor, buf, strlen(buf) + 1, 0) < 0) {
cerr << "cannot send data ";
close(socketDescriptor);
exit(1);
}
