Libnet is intended mainly for game programming; at least, the programs
it produces are only meant to communicate with each other.  It does
use standard protocols for Internet communication (UDP and more
recently TCP), but it's not meant to talk to normal Internet programs
like FTP servers, web servers and so on.

If you only want your programs to talk to each other) then Libnet may
be what you're looking for.  The emphasis is on providing a simple
networking interface, which is the same for all supported network
types, so that your program doesn't really need to know what type of
network it is using.  At present the only support is for Internet
communication using Win95's Winsock in djgpp or Berkeley sockets on
Unix systems.  An IPX driver is being written, as are serial and
DOS-based internet drivers (dial-up via PPP and hopefully also network
cards).

If however you are writing an application that needs direct access to
TCP/IP, as the Subject: implies, Libnet probably won't help you.  You
could try either Dan Hedlund's WSOCK library or Indrek Mandre's
libsocket library; both provide access to Windows 95's Winsock from
djgpp.  There are packages that allow you to access the Internet
directly, without using the Winsock, but I have never tried any of
them.  Look at TCPlib perhaps.

Libnet can be downloaded from:

WSOCK, libsocket and TCPlib are all linked from:
