These sockets mentioned by me are for sending only. Receiving is done by one 
central socket 
for all connections, which works because traffic etc. is not a problem. Okay 
some of that things 
are this way because I didn't understand all concepts when initially building 
this DLL, but I didn't 
have much time back then.

The question is, how should the DLL sitting on top of my communication dll use 
thread attach? It has no
access to the socket whatever, it only has init_communication, 
close_communication and send. All work with
a handle (integer) the communication dlls assigns a new connection within 

How can I solve my problem? Which thread does the socket belon to now? Does it 
belong to the thread in 
the dll sitting on top of my communication dll? If yes, why does closing that 
socket within the execute method
of this thread problems? Is it because the socket might have been created by 
that dll but within another context?
If created from the same thread and destroyed by the same thread there would be 
no problem?
