 |
|
Hi everybody,
all is in this title, Who can do it ?
I think iit's very important to know how to do it, because when I see the pspsdk and the number of function that appears in list of NID, I think it's very pity.
thx,

This should work. Thanks to moonlight for helping me with it a while back.
| Code: | // From PspPet's PSARDUMPER
static u32 FindProc(const char* szMod, const char* szLib, u32 nid)
{
SceModule* modP = sceKernelFindModuleByName(szMod);
if (modP == NULL)
{
printf("Failed to find mod '%s'\n", szMod);
return 0;
}
SceLibraryEntryTable* entP = (SceLibraryEntryTable*)modP->ent_top;
while ((u32)entP < ((u32)modP->ent_top + modP->ent_size))
{
if (entP->libname != NULL && strcmp(entP->libname, szLib) == 0)
{
// found lib
int i;
int count = entP->stubcount + entP->vstubcount;
u32* nidtable = (u32*)entP->entrytable;
for (i = 0; i < count; i++)
{
if (nidtable[i] == nid)
{
u32 procAddr = nidtable[count+i];
// printf("entry found: '%s' '%s' = $%x\n", szMod, szLib, (int)procAddr);
return procAddr;
}
}
printf("Found mod '%s' and lib '%s' but not nid=$%x\n", szMod, szLib, nid);
return 0;
}
entP++;
}
printf("Found mod '%s' but not lib '%s'\n", szMod, szLib);
return 0;
}
static void my_function(void)
{
int (* power) (int);
reboot = (void *)FindProc("scePower_Service", "scePower_driver", 0x0442D852);
if (!reboot)
{
sceKernelExitGame();
}
else
{
reboot(0);
}
} |
This is an example and uses the function scePower_0442D852
In this example, it is called asreboot(0) because the function only seems to work that way, but obviously you would change the contents of the brackets to whatever arguments you would be sending.
I think there is a more efficient way of doing this but for me it works :)

Hi jas0nuk,
Thx for the answer, She look like great and easy.
But, when I look your example with "scePower_Service", I can see that
| Code: | | reboot = (void *)FindProc("scePower_Service", "scePower_driver", 0x0442D852); |
,appears 3 args, const char* szMod (scePower_Service), const char* szLib (scePower_driver) , u32 nid (0x0442D852).
I can understand 2nd and 3th args but not the 1st, where you can find this ?
So, for example, I need "sceUtilityDeleteNetParam" with NID 0x9ce50172.
I guess that function need 1 arg who's will the number of config to delete.
How to comunicate to this function this number ?? :) damn
If you can do it, you'll be the best ;)

lol ! not for me .... nobody functions is explains, just the name, but also help in many case.
jas0nuk>
I suppose that the function can use as it :
| Code: | int ret;
int num_profil = 1;
ret = sceUtilityDeleteNetParam( num_profil );
fprint( "function return : %i",ret); |
How give "num_profil" to the function ?
I don't understand very much your line, sorry I'm bad ;)
Thx for all jas0nuk |

I'm not sure what you're asking... but if you want to send an argument to the function, you could just call it as...
| Code: | | reboot(num_profil); |
after using the line I showed you before |

I'm back again :) !
I try your sample, it's appear correctly when I compile it, but when I execute it, he crash on line in FindProc :
| Code: | | SceModule* modP = sceKernelFindModuleByName(szMod); |
when I call it by :
| Code: | | DeleteNetParam = (void *)FindProc("sceUtility_driver", "sceUtility_netparam_internal", 0x9CE50172); |
And finish to black screen/shutdown.
Damn, I smelled come the end of it, but not.
Are you an idea about this problem ?
( PS : good luck for 0x89 Jas0nuk ) |

| Most likely looks like you are just not running in kernel mode. |

This is a sample of my code
| Code: | // *** MODULE INITIALISATION ***
PSP_MODULE_INFO("TestWifi",0x1000,1,1);
PSP_MAIN_THREAD_ATTR(0);
PSP_MAIN_THREAD_STACK_SIZE_KB(32);
//*** CallBack section *******
// ........
// ************************
static u32 FindProc(const char* szMod, const char* szLib, u32 nid)
{
//*********** BLACKSCREEN HERE *****************
SceModule* modP = sceKernelFindModuleByName(szMod);
if (modP == NULL)
{
pspDebugScreenPrintf("Failed to find mod '%i'\n", szMod);
return NULL;
}
SceLibraryEntryTable* entP = (SceLibraryEntryTable*)modP->ent_top;
while ((u32)entP < ((u32)modP->ent_top + modP->ent_size))
{
if (entP->libname != NULL && strcmp(entP->libname, szLib) == 0)
{
// found lib
int i;
int count = entP->stubcount + entP->vstubcount;
u32* nidtable = (u32*)entP->entrytable;
for (i = 0; i < count; i++)
{
if (nidtable[i] == nid)
{
u32 procAddr = nidtable[count+i];
// printf("entry found: '%s' '%s' = $%x\n", szMod, szLib, (int)procAddr);
return procAddr;
}
}
pspDebugScreenPrintf("Found mod '%s' and lib '%s' but not nid=$%x\n", szMod, szLib, nid);
return NULL;
}
entP++;
}
pspDebugScreenPrintf("Found mod '%s' but not lib '%s'\n", szMod, szLib);
return NULL;
}
int sceUtilityDeleteNetParam(int NetParam)
{
int (*DeleteNetParam) (int);
DeleteNetParam = (void *)FindProc("sceUtility_driver", "sceUtility_netparam_internal", 0x9CE50172);
if (DeleteNetParam <> NULL )
if(sceUtilityCheckNetParam(NetParam) != 0) pspDebugScreenPrintf("Profil %i inexistant\n",NetParam);
else return DeleteNetParam(NetParam);
return -1;
} |
I think I was in kernel mode, but I haven't enought knowledge about kernel mode, so ... . |

maybe error on sceUtility_driver
try this :)
| Code: | ...
DeleteNetParam = (void *)FindProc("sceUtility_Driver", "sceUtility_netparam_internal", 0x9CE50172);

Damn !! TyRaNiD have the good answer, I'm not running in kernel mode my thread ....
humm ... How could be it ?? Simply change the attribute of sceKernelCreateThread ? |

no
your code in kernel mode
but PrxName is wrong :P
try this to test :)

Of course the real question is why dont you create a new file called something like netparam.S (note the capitalisation) and put into it:
| Code: | .set noreorder
#include "pspstub.s"
STUB_START "sceUtility_netparam_internal",0x40010000,0x00040005
STUB_FUNC 0x072DEBF2,sceUtilityCreateNetParam
STUB_FUNC 0x9CE50172,sceUtilityDeleteNetParam
STUB_FUNC 0xFB0C4840,sceUtilityCopyNetParam
STUB_FUNC 0xFC4516F3,sceUtilitySetNetParam
STUB_END
|
Link that with your code and jobs a good un... |

I don't ask anymore, but, how to link this in your main.c ?
I tryed (note the capitalisation ;) ) :
| Code: |
#include "netparam.S"
..
int sceUtilityDeleteNetParam(int);
..
int main(void){
..
pspDebugScreenPrintf("Code retour : %i",sceUtilityDeleteNetParam(2));
..
}
|
and launch the makefile, he warm me about netparam.S and a lot of stuff invalid preprocessing directive.
Maybe my makefile is bad, maybe I mistake a line, I don't know anymore.
Can you give me a tips again :). I know I know, I bored you :)
thx a lot for all ;) |

| Well if you are using a standard Makefile from PSPSDK then just add to the 'OBJS =' line netparam.o, if you are not using a standard makefile then you are probably on your own. You only need to assemble the file with something like psp-gcc -I/usr/local/pspdev/psp/sdk/include -c -o netparam.o netparam.S and link in the object. |

Ohhh my god !!! TyRaNID you are sooo good !!
This code run correctly and I can delete a net parameters finally.
well, I post my sample for turn the post to [RESOLVE] and do it.
MAIN.C :

// *** MODULE INITIALISATION ***

}
pspDebugScreenInit();
return thid;
}
/*------------------------------------------------------------------------------*/
int sceUtilityDeleteNetParam(int);
int main(void)
{
SetupCallbacks();
int err = pspSdkLoadInetModules();
if (err != 0) {
pspDebugScreenPrintf("pspSdkLoadInetModules failed with %x\n", err);
sceKernelDelayThread(5*1000000); // 5 sec to read error
return 1;
}
// print available connections
pspDebugScreenPrintf("available connections:\n");
int i;
for (i = 1; i < 100; i++) // skip the 0th connection
{
if (sceUtilityCheckNetParam(i) != 0) break; // no more
char name[64];
sceUtilityGetNetParam(i, 0, (netData*) name);
pspDebugScreenPrintf("%i: %s\n", i, name);
}
pspDebugScreenPrintf("Test effacement derniere config de connection:\n");
pspDebugScreenPrintf("Code retour effacement : %i",sceUtilityDeleteNetParam(--i));
sceKernelExitGame();
return 0;
} |
NETPARAM.S :

include $(PSPSDK)/lib/build.mak |
A little last question, where you got the values for STUB_START and what mean this 0x40010000 and 0x00040005
For continue, I search for use sceUtilitySetNetParam and other
Thx to TyRaNID and jas0nuk |
