Re: [Dev-C++] About headers like socket.h

[Ferdinando F. <s2...@st...>]

As far as I know, you can use Windows headers, that on TCP are very
similar to Linux ones. Well, not by header names, but you'll find a
socket, listen, accept, setsockopt, etc. functions with same arguments,
and so on: you'll only need to use send intead of write and recv intead of
read to do I/O on socket. This is the way Microsoft wished to be posix 1.0
compliant.

To do this you need to link a lib (winsock, or something similar, which
you should initialize before any network call with WSASturtup) and a
network header, but I don't remember its name. If you give a look on MSDN
on line. i.e. searching for socket: data over there are VisualC-oriented,
but Dev C++'s behaviour is identical.

I hope that's helpful to you.

Bye, Ferdinando
