Go Systems Programming

A simple example

In this subsection, we will present a simple program that creates two goroutines. The name of the sample program will be aGoroutine.go and will be presented in three parts; the first part is the following:

package main 
 
import ( 
   "fmt" 
   "time" 
) 
 
func namedFunction() { 
   time.Sleep(10000 * time.Microsecond) 
   fmt.Println("Printing from namedFunction!") 
} 

Apart from the expected package and import statements, you can see the implementation of a function named namedFunction() that sleeps for a while before printing a message on the screen.

The second part of aGoroutine.go contains the following Go code:

func main() { 
   fmt.Println("Chapter 09 - Goroutines.") 
   go namedFunction() 

Here, you create a goroutine that executes the namedFunction() ...
