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.
