Hi there Maniac,

You responded with a comment to my question below on 17th May,
apologies for not returning sooner, I was travelling with work.

I would like to reactivate this. I have full access to the machine and
have set the registry to allow setting of TOS. So all I need to do is
to change the code.

Original Question: 

I inherited some C++ code which generates UDP traffic from XP.

I wish to add some code to mark the DSCP field of the IP packets.

I understand that I need to add "setsockopt" after the socket is
created, but as a non programmer, Im unsure how to proceed.

Best regards

Brendan
