## golang协程异步io复用模型

每个fd的封装类型都需要组合internal/poll.FD类型，然后由后者去做io  

对于进程继承来的标准fd(0,1,2)，先包装一下，然后internal/poll.FD依然使用阻塞方式去io  

对于自己打开的fd，也是先包装一下，然后internal/poll.FD统一使用异步复用方式进行io，golang使用协程把它模拟成阻塞方式  

```

listener/conn-----net.(*netFD)-------

                                     |-------internal/poll.(*FD)----------runtime跨平台支持poll

                  os.(*file) --------        (支持blocking和poll)

```

## libuv事件驱动异步io复用模型

```

listener/conn------net.(*netFD)------

                                     |--------go-libuv/poll.(*PollDesc)---不需要runtime支持

                   os.(*file)--------         (现在只支持linux)

                   (not yet)

```

#### usage

```

package main

import (

	"log"

	"github.com/xujintao/go-libuv/net/http"

	"github.com/xujintao/go-libuv/poll"

)

func main() {

	log.SetFlags(log.LstdFlags | log.Lshortfile)

	http.ListenAndServe(":8080")

	poll.Wait()

}

```
