Passing data into callbacks

[Graham Leggett]

Hi all,

I have a callback that gets called when a socket becomes ready to be 
accepted, and so far that works fine.

In order to properly accept the socket and set up various parameters, I 
have to pass additional information about the socket to the callback, 
and I am struggling to see a way to do this without using a global variable.

Am I missing something?

Regards,
Graham
