Print the address or pointer for value in C

I want to do something that seems fairly simple. I get results but the problem is, I have no way to know if the results are correct.

I'm working in C and I have two pointers; I want to print the contents of the pointer. I don't want to dereference the pointer to get the value pointed at, I just want the address that the pointer has stored.

I wrote the following code and what I need to know is if it is right and if not, how can I correct it.

/* item one is a parameter and it comes in as: const void* item1   */
const Emp* emp1 = (const Emp*) item1; 

printf("\n comp1-> emp1 = %p; item1 = %p \n", emp1, item1 );

While I'm posting this (and the reason it is important that it is correct) is that I eventually need to do this for a pointer-to-a-pointer. That is:

const Emp** emp1 = (const Emp**) item1;
Solution

  • What you have is correct. Of course, you'll see that emp1 and item1 have the same pointer value.
