Curiosity of retrieving bytes of a data-type

Code:

---


const int GetByte(void* i, unsignedchar byte)
{
  return(int)((&i)[byte]);
 
 
}

---

The given function ( i believe ) will return the specified byte of a given type. I have been using this to identify endian-ness, but I was wondering if there is a way to make this work on temporary.

Such as

Code:

---

GetByte("A",0);




---

will show the address, not the actual byte value
Although

Code:

---

GetByte(1,0);

---

works as expected.

I am sure I am just blindly over-looking some simple logic, but I thought I would ask.

Thank you sincerely.

Code:

---

const int GetByte(void* i, unsigned char byte)
{
  return ( ( char* ) i )[ byte ];
}

---

you are taking the void* and using its address '&i' rather than i itself
