How to call a 32-bit machine code introduced in pointer or array from c + +?

[Vedran L]

I have introduced 32-bit machine code into an array or pointer, is there any way to call this pointer and run the code? I'm using Dev C + + Win32

 

[MooseBoys]

void runMyCode(int* pCode){
void (*func)();
func = (void*)pCode;
func();
}

Note that this will be blocked at runtime in Windows Vista and above by DEP.

Most C compilers allow you to embed assembly into your source, using

_asm {
code
}

You can probably load the address of your buffer into a register, and then jmp to that address in the _asm block.

There might be an easier way, but its been a while since I coded in C.

Another way might be to declare a void function pointer, and set that pointer to the address of your buffer, then call it as if it were a function.
