Help/Support how return by (void) in string

[Ianouar3G 16.1k 8 8.1.3]

hi gays   how return by (void)

 

                  ; Quest::mpNumber::setmpNumber(void)
 __ZN5Quest8mpNumber11setmpNumberEv

 

 

 

Is this correct way

 

int (*old__ZN5Quest8mpNumber11setmpNumberEv)();

int $__ZN5Quest8mpNumber11setmpNumberEv()
{
   return 99999;
}

%ctor {

    MSHookFunction(((int*)MSFindSymbol(NULL, "__ZN5Quest8mpNumber11setmpNumberEv")),(int*)$__ZN5Quest8mpNumber11setmpNumberEv,(void**)&old__ZN5Quest8mpNumber11setmpNumberEv);
 }

[KingRalph 818 9.3.5]

This is how I would call a void argument in ms hook. Someone with more experience can correct me if I'm wrong

 

int $__ZN5Quest8mpNumber11setmpNumberEv()
{
   %orig(99999);
}

 

Always remember that void functions don't "return" anything. You have to call the original argument with %orig

No just treat the void as what it would be if it was not a void. That symbol would be an int, so just put
 

int $__ZN5Quest8mpNumber11setmpNumberEv{
return 9999;
}

Actually you are correct, I didn't read your first post fully yeah you're good to go :thumbsup:

int (*old__ZN5Quest8mpNumber11setmpNumberEv)();

 

int $__ZN5Quest8mpNumber11setmpNumberEv   /-------- if not use "()" stile ger errors

 

{

   return 99999;

}

 

%ctor {

 

    MSHookFunction(((int*)MSFindSymbol(NULL, "__ZN5Quest8mpNumber11setmpNumberEv")),(int*)$__ZN5Quest8mpNumber11setmpNumberEv,(void**)&old__ZN5Quest8mpNumber11setmpNumberEv);

 }

try this

 

int (*old__ZN5Quest8mpNumber11setmpNumberEv)();

int $__ZN5Quest8mpNumber11setmpNumberEv()
{   
return 99999;
}

%ctor{    
MSHookFunction(((int*)MSFindSymbol(NULL, "__ZN5Quest8mpNumber11setmpNumberEv")),(int*)$__ZN5Quest8mpNumber11setmpNumberEv,(int**)&old__ZN5Quest8mpNumber11setmpNumberEv); 
}

Actually what he supposed to have correct in the first post was indeed. There is no reason to edit it

@@castix he didn't change the third void to int the first time, but i don't know if that matters or not i use my own way

@@shmoo the third is always (void**)

Oh when I did that method a couple times I would always change the third method to whatever the first and second methods were and it would work...
