atomic.StoreInt32() Function in Golang With Examples

In Go language, atomic packages supply lower-level atomic memory that is helpful is implementing synchronization algorithms. The StoreInt32() function in Go language is used to atomically store val into *addr. This function is defined under the atomic package. Here, you need to import “sync/atomic” package in order to use these functions.

Syntax:

func StoreInt32(addr *int32, val int32)

Here, addr indicates address.

Note: (*int32) is the pointer to a int32 value. However, int32 contains the set of all signed 32-bit integers from -2147483648 to 2147483647.

Return value: It stores the val into *addr and then can be returned when required.

Example 1:

// Program to illustrate the usage of 
// StoreInt32 function in Golang 
  
// Including main package 
package main 
  
// importing fmt and sync/atomic 
import ( 
    "fmt"
    "sync/atomic"
) 
  
// Main function 
func main() { 
  
    // Defining variables for  
    // the address to store the val 
    var ( 
        x int32 
        y int32 
    ) 
  
    // Using StoreInt32 method  
    // with its parameters 
    atomic.StoreInt32(&x, 65) 
    atomic.StoreInt32(&y, 3455) 
  
    // Displays the value stored in addr 
    fmt.Println(atomic.LoadInt32(&x)) 
    fmt.Println(atomic.LoadInt32(&y)) 
} 

Output:

65
3455

Here, first, the int32 value is stored in the addresses defined then they are returned using the LoadInt32() method above.

Example 2:

// Program to illustrate the usage of 
// StoreInt32 function in Golang 
  
// Including main package 
package main 
  
// importing fmt and sync/atomic 
import ( 
    "fmt"
    "sync/atomic"
) 
  
// Main function 
func main() { 
  
    // Defining variables for  
    // the address to store the val 
    var ( 
        x int32 
    ) 
  
    // Using StoreInt32 method  
    // with its parameters 
    atomic.StoreInt32(&x, 8943) 
  
    // Loading the stored val 
    z := atomic.LoadInt32(&x) 
  
    // Prints true if values  
    // are same else false 
    fmt.Println(z == x) 
  
    // Prints true if addresses 
    // are same else false 
    fmt.Println(&z == &x) 
} 

Output:

true
false

Here, the value stored and loaded are the same so true is returned but their addresses are not the same so false is returned in that case.
