[fpc-pascal] How to implement a simple tcp/ip connection?

[Giuliano Colla]

I'm struggling with a similar problem. It would appear that the easiest 
way would be just take advantage of the Sockets unit. You only must 
define some more constants, such as SO_REUSEPORT and SOCK_NONBLOCK which 
are missing in fpc.

I just made some preliminary tests, and it looks like it's not so 
difficult to implement something quite compatible with Delphi 
philosophy. The SOCK_NONBLOCK flag is one of the keys.

Now I'm planning to look in more detail the old Delphi implementation, 
in order to see how they were tacking advantage of Libc. If you're 
interested I'll let you know my results.
