How to flush a socket

[iceman]

Hi all,
HOw can I flush the socket.
eg
how can I ensure that the send takes place immediately

if (send(socketDescriptor, buf, strlen(buf) + 1, 0) < 0) {

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

sorry it was supposed to be,

if (send(socketDescriptor, buf, strlen(buf) + 1, 0) < 0) {

cerr << "cannot send data ";
close(socketDescriptor);
exit(1);
}

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.

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!
