Porting Winsock to Linux Sockets

Question

I have a program that does some networking using Winsock, and one of our requirements right now is to port over our program to Linux. The only thing stopping us from doing t

Answer 1

The only calls that make porting difficult are the WSA* calls.

WSAStartup() -> nop WSACleanup() -> nop

Socket/setsockopt -> socket/setsockopt

Under *nix, sockets are blocking by default and it's not necessary or possible to use that weird setsockopt call to fiddle with it.

ioctlsocket -> ioctl

Under *nix we don't like asynchronous sockets much and prefer to use the select() system call.

Unfortunately as the original socket() in Winsock was broken in some cases, you probably used WSASocket() and so have to convert those calls.
