That depends whether you are little endian or not, and whether you translate the address to network order before passing in to sockets like I do, eg.:

address.sin_addr.s_addr = htonl( destination.GetAddress() );

If I am not wrong, inet_addr seems to OR the a.b.d.c in the reverse order

i.e. instead of

unsigned int destination_address = ( a << 24 ) | ( b << 16 ) | ( c << 8 ) | d;

if should be

unsigned int destination_address = ( d << 24 ) | ( c << 16 ) | ( b << 8 ) | a;

Anyone ever considered SCTP? Seems like an interesting mix of TCP and UDP features and could maybe provide a shortcut allowing one to get UDP with benefits without having to write the hard parts.

[...] I’m going to try to write my own chat software soon. This is part of my research. I’m thinking a lot about how much I should try to handle in my own code and how much I should rely on the functionality that is already there in Unix systems. BSD sockets [...]

Years later and you’re still helping out those who ask. My hat goes off to you, sir; thanks for the fine article.

Could be. Try to find an example for your compiler that links and reverse engineer from there.

I’m having problems with linker errors on windows, all of the functioncalls to members of the winsock2 library are generating linker errors, I tried to link different files:
wsock2.lib, wsock2.dll, winsock2.lib, winsock2.dll, ws2_32.lib, ws2_32.dll

Maybe the Dev-C++ compiler is causing the problem?

It changes a lot, the second code is incorrect and is equivalent to always returning true.
