How to get a pointer's value or depointerize it

I was wondering if it's possible to make a pointer not a pointer.

The problem is I have a function that accepts a pointer for a parameter for me to easily get a value to that pointer. It's a simple int, so I was wondering if I could just get that value without needing to send around a pointer wherever I want the value to land.

I don't want the function to return the value as an int, as it's giving a value to 2 pointers!

Solution

  • To get the value of a pointer, just de-reference the pointer. 

    int *ptr;
int value;
*ptr = 9;

value = *ptr;

    value is now 9.

    I suggest you read more about pointers, this is their base functionality.
