WLAN in user mode

[Zwergengraf]

Hi there,
I'm developing a game that uses WLAN and a GFX-Lib(I want to use OSLib). The problem is: WLAN has to be initialized in kernel mode, and the gfx-libs don't want to work in kernel mode. I heard that you can use WLAN in user mode, but I didn't find a real example about this. Could someone _please_ post a complete example on how to use WLAN in user mode (source+makefile)? If it's possible, without threading. I have read some other threads about this, but the examples were not complete or didn't work. This makes me really crazy, because I spent a lot of time in trying many things before I noticed that my gfx-libs don't work in kernel mode...

Use

sceUtilityLoadNetModule(PSP_NET_MODULE_COMMON);
sceUtilityLoadNetModule(PSP_NET_MODULE_INET);

to load the modules in usermode rather than having to in kernel.

Hi,
could you please post a complete example? I tried the source from HERE, but it doesn't work. I get one of these errors: 00000017 when it should initialize the PSP_NET_MODULE_COMMON, or the game starts but returns to XMB and sayes 8002013A.

I forgot to mention you have to be running in the 3.xx kernel

// Load modules
sceUtilityLoadNetModule(PSP_NET_MODULE_COMMON);
sceUtilityLoadNetModule(PSP_NET_MODULE_INET);

// Get connections

// Connect
int connectTo(int connectNum)
{
	int err;
	int stateLast = -1;

	// WLAN
	err = pspSdkInetInit();
	if (err != 0)
	{
		printf("Error pspSdkInetInit() \n");
		sceKernelDelayThread(2000*1000);
	}

	err = sceNetApctlConnect(connectNum);
	if (err != 0)
	{
		printf("Error sceNetApctlConnect() \n");
		sceKernelDelayThread(2000*1000);
	}

	sceNetResolverCreate(&resolverId, resolverBuffer, sizeof(resolverBuffer));
    
	while (1)
	{
		int state;
		int err = sceNetApctlGetState(&state);
		if (err != 0)
		{
			printf("Error at state %i \n", state);
			sceKernelDelayThread(2000*1000);
			return 0; // connection failed
		}

		if (state > stateLast)
		{
			printf("State %i \n", state);
			stateLast = state;
		}

		if (state == 4)
			break;  // connected with static IP

		// wait a little before polling again
		sceKernelDelayThread(200*1000); // 200 ms
	}

	return 1;
}

Okay thanks, I tried this code:

----------

#include <pspkernel.h>
#include <pspdebug.h>
#include <pspsdk.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <psputility_netmodules.h>
#include <psputility_netparam.h>
#include <pspwlan.h>
#include <pspnet.h>
#include <pspnet_apctl.h>

#define printf pspDebugScreenPrintf

PSP_MODULE_INFO("test", 0, 1, 1);

/* Exit callback */
int exit_callback(int arg1, int arg2, void *common)
{
   sceKernelExitGame();
   return 0;
}

/* Callback thread */
int CallbackThread(SceSize args, void *argp)
{
   int cbid;

   cbid = sceKernelCreateCallback("Exit Callback", exit_callback, NULL);
   sceKernelRegisterExitCallback(cbid);
   sceKernelSleepThreadCB();

   return 0;
}

/* Sets up the callback thread and returns its thread id */
int SetupCallbacks(void)
{
   int thid = 0;

   thid = sceKernelCreateThread("update_thread", CallbackThread,
                 0x11, 0xFA0, PSP_THREAD_ATTR_USER, 0);
   if(thid >= 0)
   {
      sceKernelStartThread(thid, 0, 0);
   }

   return thid;
}

int connectTo(int connectNum)
{
	int err;
	int stateLast = -1;

	// WLAN
	err = pspSdkInetInit();
	if (err != 0)
	{
		printf("Error pspSdkInetInit() \n");
		sceKernelDelayThread(2000*1000);
	}

	err = sceNetApctlConnect(connectNum);
	if (err != 0)
	{
		printf("Error sceNetApctlConnect() \n");
		sceKernelDelayThread(2000*1000);
	}

	//sceNetResolverCreate(&resolverId, resolverBuffer, sizeof(resolverBuffer));
    
	while (1)
	{
		int state;
		int err = sceNetApctlGetState(&state);
		if (err != 0)
		{
			printf("Error at state %i \n", state);
			sceKernelDelayThread(2000*1000);
			return 0; // connection failed
		}

		if (state > stateLast)
		{
			printf("State %i \n", state);
			stateLast = state;
		}

		if (state == 4)
			break;  // connected with static IP

		// wait a little before polling again
		sceKernelDelayThread(200*1000); // 200 ms
	}

	return 1;
}

int main(){
    SetupCallbacks();
    pspDebugScreenInit(); 
    // Load modules
    if (sceUtilityLoadNetModule(PSP_NET_MODULE_COMMON) < 0)
    {
      printf("Error, could not load PSP_NET_MODULE_COMMON\n");
      sceKernelSleepThread();
    }
    if (sceUtilityLoadNetModule(PSP_NET_MODULE_INET) < 0)
    {
      printf("Error, could not load PSP_NET_MODULE_INET\n");
      sceKernelSleepThread();
    } 
    printf("Connecting...");
    connectTo(1);
    sceKernelSleepThread();
    return 0;
}

----------
and this makefile:
----------

TARGET = netsample
OBJS = main.o

INCDIR = 
CFLAGS = -O0 -G0 -Wall -g
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

PSP_FW_VERSION = 380

LIBDIR =

EXTRA_TARGETS = EBOOT.PBP

PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

----------

compiled it with "make kxploit", then I put it into GAME and the program displayed:

Connecting...Error pspSdkInetInit()
Error sceNetApctlConnect()
Error at state -2012413952

At least it loads the modules, thats good! But what is wrong now? I hope you (or someone else ) can help me.
Thanks, Zwergengraf

Hi.

Add BUILD_PRX=1 to your Makefile.

Compile with make only.

Place the EBOOT in a directory on GAME3XX.

Run.

[Zwergengraf]

OMFG, IT WORKS! Ouh, I can't say how much you have helped me with this! I want to thank you two very much!

Edit: Well, it doesn't work 100%: everytime I try to draw an image with blitAlphaImageToScreen, it crashes. It doesn't fail at loading the image. What's wrong?

Maybe buffer overflow?
