[Coding] IRC client, need some help

Hello
I have tried a bit by myself but it looks like coding IRC client is not as easy as I wanted
There are 3 header files I tried to use:
#include < MLlib.h >
#include < sys/types.h >
#include < sys/socket.h >
But last two gives errors, dunno why, maybe DevkitPPC doesn't like Linux header files :P

My question is what libraries (and eventually where search for them) should I use to this task?

I'm using Linux with DevkitPPC and MLlibrary for now

Thank You for advance

EDIT: Nevermind, fixed.

What the... I have been copying with files...I will try editing post, maybe there is some error, if that won't help I will write without [ code] Tag <_<
Sorry for problems
One sec

EDIT #1
Fixed, I had to put space between "<" and ">" and text...strange...it shouldn't parse unknown tags in < >

EDIT #2
I had somewhere Python simple script to connect to certain server so I will probably use it for tries but first I have to know what libraries I will need :(

I think you want to import network.h, it should be in the libogc include dir (of you have the libogc source, it is in the lwip, lightweight ip, directory).

Call the function net_init() which returns a signed int, non-zero is an error.
net_socket( int, int, int ); returns a socket file descriptor, INVALID_SOCKET upon error.
Same as BSD sockets in general, but all functions are prefixed with net_.

EDIT:
For a simple example look at the PCToWii application, it has a Wii server, and the source is available. Pretty simple code, just look at the main function. It comes packed as a VC project, so no Makefile, but if you have Windows and VC Express, it makes things even easier.

Thank You for reply :)
Now to results:

1) I have included network.h and it compiled without any errors or warnings so it looks like it passed
2) I have checked PCtoWii and found main section with that Init You mentioned, now things are going easier :)

So I guess first thing is to try define in some way server adress even static for now, port, channel and such things then trying to connect to it right?

Oh one more question a bit out of that problem but not worth of creating extra topic
Does someone know some command to make Home Button exit to HomeBrew Channel or Wii Menu? Not important which one of them will be, just to not have to do all things with Wii buttons :P
I have tried several from MLlib but none of them worked so far... heh same problem was long time ago with power off function for Nintendo DS :D

Thank You for advance and have a nice day/night

EDIT #1
Hahaha I wrote some code and made fatal code dump error xD now to track where...where...where...

EDIT #2
Looks like it was some background problem, I will mess with it later since I have white font :D
other problem is I can't overcome this:

main.c:51: error: 'sockaddr_in' undeclared (first use in this function)
main.c:52: error: request for member 'sin_port' in something not a structure or union

this is about this fragment:

sockaddr_in = sin;

sin.sin_port=htons(6667);

sin.sin_addr.s_addr=INADDR_ANY;

sin.sin_family=AF_INET;

I wonder what is a problem...in PCtoWii application source code it exists just with itself

I don't know why it's just sockaddr_in in the PCToWii code, but there's no typedef for sockaddr, sockaddr_in and hostent, and probably some other structs.
Try using struct sockaddr_in instead.

struct sockaddr_in {
  u8 sin_len;
  u8 sin_family;
  u16 sin_port;
  struct in_addr sin_addr;
  s8 sin_zero[8];
};

If you don't have experience writing networking code, you might want to have a look at a BSD socket tutorial, like Beej's Guide to Network Programming.

Yeah I don't have much experience, I had some tries but this time it's serious, with "thousand" of tutorials opened :D with Yours as well :)
I made some of this net_ commands and I got some responds from variables, most are zeros so probably it's ok (as man socket says) but net_accept turned -7 so it's probably some error... I will provide that fragments, maybe...no, not maybe...for sure I messed something up...maybe because of using many tutorials at once :D

let's see, I have this thing (many comments are there because of typing from them as examples and such things):

I made some "corrections" but it's still not that :P Dolphin emu says that:
net_init - 0

net_send - 0
net_receive - 0
net_accepte - -12

I'm sure I made some mistakes but dunno what kind of and where...sockets are really annoying :P

Thank You for advance

I don't know about your network problem, sorry... but for exiting the application, just use ML_Exit() et it will return to the loader (HBC). But you have to free all image data before if you want it to be fully working.
ML_DeleteImage(&imageData);

Hope it helps ;)

Oh and, if you want to shut down the Wii, use that :
ML_ShutdownWii();
for the moment . It's atm in fact SYS_ResetSystem(SYS_POWEROFF,0,0); but in next release that will be a nice exit with freeing and so on ;)
