Hi
i dont' understn what is the difference between :
ch := make(chan bool,1) vs. ch := make(chan bool)
this sample works well :
package main
import (
"fmt"
"sync"
)
var x = 0
func increment(wg *sync.WaitGroup, ch chan bool) {
ch <- true
x = x + 1
<-ch
wg.Done()
}
func main() {
var w sync.WaitGroup
ch := make(chan bool,1) <------it is OK , but if i
change to ch := make(chan bool) - it doesn't work
for i := 0; i < 1000; i++ {
w.Add(1)
go increment(&w, ch)
}
w.Wait()
fmt.Println("final value of x", x)
}
Thank you in advance
