GO语言的IO方法实例小结
typePipeWriter
typePipeWriterstruct{
//containsfilteredorunexportedfields
}
(1)func(w*PipeWriter)Close()error关闭管道，关闭时正在进行的Read操作将返回EOF，若管道内仍有未读取的数据，后续仍可正常读取
import( "fmt" "io" )
funcmain(){ r,w:=io.Pipe() gow.Write([]byte("helloword"))
data:=make([]byte,10) n,err:=r.Read(data) w.Close() iferr==io.EOF{ fmt.Println("executingreadreturnEOF") fmt.Println("executingreadreadsnumber",n) } n,_=r.Read(data) fmt.Println(string(data)) //helloword fmt.Println("nextreadnumber",n)//nextreadnumber0 }
