I’m doing a real-time strategic game with network support. The idea is to build
a client-server system. Actually, I can’t do anything because I haven’t
netowrk support on all multiplateform ! Could someone make TCP/IP network
support, with just the necessary funtions (please just comment the parameters
to the fcontions) ???
Anotehr question, If I build 2 applications, can I connect from the client to
the server if it is running on the same machien ?

Just go download the source code to a MUD and look at their networking
code. Sockets are really quite simple once you’ve done it once or twice.
Look on sunsite.unc.edu for the source.On Thu, 15 Oct 1998, Stephane Magnenat wrote:

Well, when the network thread started some time ago, Sam posted a
snippet of code from Maelstrom that is crossplatform between Windows
and Linux (I don’t know about BeOS) that seems to work well enough. I
can send it to you if you want. It’s not that well commented, but if
you know anything about socket-style networking, it shouldn’t be too
bad.

Yes. You just set the server to “localhost” with the right port
number, and it should work fine.On 15 Oct, Stephane Magnenat wrote:
No. That will generally not be multiplatform. It will be

The networking code in Remtris 3 (which runs on Win32 and Linux) is BSD
sockets, and the difference between the two versions is small enough to
be stashed in #ifdef’s.
BSD sockets (as an abstraction) are quite portable (except to the MacOS
it seems, they have what? TLI/STREAMS-based networking?), you can
program directly to them with a few #ifdef’s or a few wrapper functions
(easier).–

I’ve never seen Remtris, but like I said, when Sam posted that code
from Maelstrom, I was surprised how simple it was. Just a couple #ifdef’s and a few typedef’s and it was the same.

Right, which could prove to be quite a problem. I like being able to
switch between sockets like file descriptors. And I like being able to
use select, read/write, and even tossing 'em to FILE * for use with
printf and stuff. It’s really nice.On 16 Oct, Pierre Phaneuf wrote:

Why build network support into SDL when both Linux and MS-Windows already
has it? Read up on socket programming. Here is an excellent tutorial on
socket programming for Unix:

Thanks for this adresse, it is usefull.
The problem is, win32 doesn’t use exactly the same system. Does gnu-win32 can
compile UNIX program using network withouht any modifications ? Because for my
game I recompile it using mingw32 crosscompiler under Linux. Can you help me
please ?

I know Win32 doesn’t use the same system. I take it your using djggp? Or
whatever it’s called. No, it won’t crosscompile from Win32 to Linux/Unix
because all a crosscompiler does is use a different instruction set or
reformat the binary so it is compatible with the file system. Win32 uses a
slightly different parameter system for winsock. I haven’t looked for one,
but there is probably a winsock guide out there somewhere. Use one of the
search engines and look for winsock programming.

Yes, gnu-win32 lets you compile unmodified unix source code programs as windows
applications. However, they run under a slow and nasty unix emulation layer, which you
may or may not like. I suggest you keep on using mingw32 (as it will be faster than
cygwin32), but what we need is some kind of wrapper layer to allow for the different
functionality and naming conventions of the socket implementations.

There has to be one out there on the net. The Win32 calling convetion is
only slightly different from the Unix version. I find it hard to believe
someone hasn’t done it yet.
PS. Sorry about the empty post. Hit the wrong keys in Pine.
I’ll correct some misinformation with details later, but the general gist
is:
1. Yes, sockets can be used on Win32
2. Yes, mingw32 can be used to cross-compile socket code.
3. No, you don’t need the slow and nasty emulation layer
Some simple networking code is highest on my priority list right now.
I won’t include it with SDL itself, but I will put it in the examples
and demos archive.
I’ll correct some misinformation with details later, but the general gist
is:
Oh, rereading the posts I realized the emulation layer was for pure UNIX
socket code. Right. But the differences between Win32 socket code and
UNIX socket code are relatively small.
Though, as Knight pointed out, you can’t use Windows sockets with fprintf()
and fread() and friends.

So you mean mingw32 will compile unmodified Unix networking program ?
Will the Mingw32 (that is minimal) do this or not ? I think not. Have someone
already done this ?>On Sun, 18 Oct 1998, Peter Hawkins wrote:

Quick question (probably in the painfully obvious category) :
How do you READ a SDL_Color from the current palette for a surface?
setting up the palette is really obvious, but I can’t see how to read from it
without kludging it.
