# Semaphore

A simple semaphore.

## Example

```go

package main

import (

	"fmt"

	"math/rand"

	"time"

	"github.com/cydave/semaphore"

)

func doWork(workerNum int, sem semaphore.Semaphore) {

	defer sem.Release()

	fmt.Printf("Worker %d processing\n", workerNum)

	n := rand.Intn(500)

	time.Sleep(time.Duration(n * int(time.Millisecond)))

	time.Sleep(time.Duration(n * int(time.Millisecond)))

	fmt.Printf("Worker %d finished\n", workerNum)

}

func main() {

	nWorkers := 10

	sem := semaphore.New(nWorkers)

	defer sem.Close()

	for i := 0; i < 100; i++ {

		sem.Acquire()

		go doWork((i%nWorkers)+1, sem)

	}

	fmt.Println("Done!")

}
