Golang : Convert(cast) uintptr to string example

Problem:

You need a fast way to convert a variable of type uintptr to type string without using unsafe package. Such as storing a process ID (pid) into a plain text file.

Solution:

Use fmt.Sprint() function to convert the uintptr value to type string. For example:

 package main

 import (
  "fmt"
 )

 var ret uintptr = 123

 func main() {
  fmt.Println(ret)
  
 // if you need to store the value
 // into a string variable
  str := fmt.Sprint(ret)
  fmt.Println(str)
 }

output:

123

123
