In Go language, atomic packages supply lower-level atomic memory that is helpful is implementing synchronization algorithms. The StoreInt64() 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 StoreInt64(addr *int64, val int64)
Here, addr indicates address.
Note: (*int64) is the pointer to a int64 value. However, int64 contains the set of all signed 64-bit integers from -9223372036854775808 to 9223372036854775807.
Return value: It stores the val into *addr and then can be returned when required.
Example 1:
// Program to illustrate the usage of // StoreInt64 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 int64
y int64
)
// Using StoreInt64 method
// with its parameters
atomic.StoreInt64(&x, 6777676777)
atomic.StoreInt64(&y, 98877)
// Displays the value stored in addr
fmt.Println(atomic.LoadInt64(&x))
fmt.Println(atomic.LoadInt64(&y))
} |
Output:
6777676777 98877
Here, first, the int64 value is stored in the addresses defined then they are returned using the LoadInt64() method above.
Example 2:
// Program to illustrate the usage of // StoreInt64 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 int64
)
// Using StoreInt64 method
// with its parameters
atomic.StoreInt64(&x, 3654567899788)
// Loading the stored val
z := atomic.LoadInt64(&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.
