LARTC - Nov 2004 - maybe OT, Linux TCP programming

Is there a way in Linux socket programming, when using TCP sockets to be
able to require notifications of when the TCP ACK packets are received.

If I send some data over a TCP socket, I''d like to know for sure 
if the data reached its recipient. A blocking "send" call, that blocks
until all ACK''s for the data are received back, would be good enough.

If you want that, you have to make your own ''tcp'' with UDP.
Another solution
is to set a very small window size, select(2) will then return on reception
on the ACK. Set the window size to one packet in that case (~1500 bytes).

Good luck!
