dear all,
I have a problem trying to send an object through TSockets… and I do not understand what’s wrong in my code… I hope someone can help me.
what I do is like this (interactively) :
TServerSocket server(10001);
TSocket client(“localhost”, 10001);
TSocket *socket = server->Accept();
TRObject robj(“ROBY”);
client->SendObject(&robj);
and here I got a segmentation violation
root [6] client.SendObject(&robj)
*** Break *** segmentation violation
