Calling functions?

Hey, I was wondering if you could call functions from another program in C++ without using inline ASM. Like if there's any other ways.

For example, I have an address for a function and all the parameters for it. How do I call it without inline ASM? In assembly it would be call 0052A48D or something. Just wondering if you can do that in C++.

Thanks

But wait. Nevermind, cause i can't think of how to utilize function pointers with an address from a different process.

Hmm for example. With that address, if you called it using inline assembly, do you not need to specify which process or executable it's coming from?

Code:

__asm {
PUSH parameter1
PUSH parameter2
CALL function
}

Making hacks are so confusing.

Yeah that's how you call functions. But im curious how you would jmp to another module, actually i think i may know that now.

I wonder how do you load a module in your assembly program?

if the games function is:

Code:

void BULLSHITFUNCTION(int abc, bool def)
{
    //their 1337 code goes here
}

and you know where in the process its stored, use the following from a dll:

Code:

void *pBULLSHITFUNCTION(int abc, int def) = (void*)0xB4DF00D;

then you can call it using
pBULLSHITFUNCTION(123,456);
I think, not sure been a long time since I worked with function pointers

Is that using a DLL or can I just make another program to do that?

using a DLL, You could try to use CreateRemoteThread and do everything from there but a dll is easier I think

Calling functions?
