Question

I want to convert a pointer *int to its real value int, in Go language.

How do you do it?

Answer 1

Just use the * operator. For example:

var i  int = 10  // `i` is an integer, with value 10
var p *int = &i  // `p` is a pointer to an integer, its value is a memory address
var n  int = *p  // `n` is again an integer, with value 10

Once you get the hang of what’s happening, the above code can be written in a more idiomatic (and simpler) way like this, assuming that we’re inside a function:

i := 10
p := &i
n := *p
