In Go language, atomic packages supply lower-level atomic memory that is helpful is implementing synchronization algorithms. The LoadUint32() function in Go language is used to atomically load *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 LoadUint32(addr *uint32) (val uint32)
Here, addr indicates address.
Note: (*uint32) is the pointer to a uint32 value. However, uint32 contains the set of all unsigned 32-bit integers from 0 to 4294967295.
Return value: It returns the value loaded to the *addr.
Example 1:
// Program to illustrate the usage of // LoadUint32 function in Golang // Including main package package main // importing fmt and sync/atomic import ( "fmt"
"sync/atomic"
) // Main function func main() { // Assigning values to the uint32
var (
i uint32 = 57
j uint32 = 0
k uint32 = 444
l uint32 = 45646667
)
// Calling LoadUint32 method
// with its parameters
load_1 := atomic.LoadUint32(&i)
load_2 := atomic.LoadUint32(&j)
load_3 := atomic.LoadUint32(&k)
load_4 := atomic.LoadUint32(&l)
// Displays the uint32 value
// loaded in the *addr
fmt.Println(load_1)
fmt.Println(load_2)
fmt.Println(load_3)
fmt.Println(load_4)
} |
Output:
57 0 444 45646667
Example 2:
// Program to illustrate the usage of // LoadUint32 function in Golang // Including main package package main // Importing fmt and sync/atomic import ( "fmt"
"sync/atomic"
) // Main function func main() { // Declaring u
var u uint32
// For loop
for i := 3; i < 315; i++ {
// Function with AddUint32 method
go func() {
atomic.AddUint32(&u, 2)
}()
}
// Prints loaded values address
fmt.Println(atomic.LoadUint32(&u))
} |
Output:
498 // A random value is returned in each run
In the above example, the new values are returned from AddUint32() method in each call until the loop stops, LoadUint32() method loads these new uint32 values. And these values are stored in different addresses which can be random one so, the output of the LoadUint32() method here in each run is different. So, here a random value is returned in the output.
