Assuming I have a memory location that I want to copy data to, and I have that address in a pointer, Is it possible to copy data at that location via MOV instruction and inline assembly.Or basically how would I copy data to a memory location via inline assembly.
In the code snippet I have provided below, I am just copying my value the the eax
register then copying from eax
register to some out value, whereas i would like to copy it to some memory address.
In short what is in the eax register I would like to store in the address pointed by outpointer
is it possible or is there a better way to do it in inline assembly?
#include <stdio.h>
#include <iostream>
using namespace std;
int func3(int parm)
{
int out =0;
// int *outpointer =&out;
//what is in the eax register I would like to store
//in the address pointed by outpointer
asm("mov %1 ,%%eax\n\t""mov %%eax, %0": "=r"(out) : "r"(parm));
// cout<<outpointer;
return out;
}
int main(int argc, char const *argv[])
{
int x{5};
int y{0};
y = func3(x);
cout<<y;
return 0;
}
