Go Sample Example - Atomic Pointer

This repository demonstrates how to atomically load and store a pointer value in Go using the sync/atomic package. It showcases safe concurrent updates to pointer values, ensuring data integrity across goroutines.

📖 Information

• This example covers the use of atomic operations to load and store a pointer value in a thread-safe manner.
• It demonstrates the use of `atomic.Value` for storing and retrieving pointer values concurrently between goroutines.
• The example includes updating the value in a separate goroutine and safely retrieving it using atomic operations.

💻 Code Example

package main

import (
	"fmt"
	"sync/atomic"
)

func main() {

	// Atomic Pointer
	// demonstrate how to atomically load and store a pointer value

	var data atomic.Value

	// Store an initial value
	data.Store("Initial Value")

	// Load and print the current value
	fmt.Println("Current Value:", data.Load())

	// Start a goroutine to change the value
	go func() {
		data.Store("New Value")
	}()

	// Load and print the new value
	fmt.Println("New Value:", data.Load())
}

🏃 How to Run

1. Make sure you have Go installed. If not, you can download it from here.
2. Clone this repository:

git clone https://github.com/Rapter1990/go_sample_examples.git

3. Navigate to the 025_atomic_counters/005_atomic_pointer directory:

cd go_sample_examples/025_atomic_counters/005_atomic_pointer

4. Run the Go program:

go run main.go

📦 Output

When you run the program, you should see an output similar to:

Current Value: Initial Value
New Value: New Value
