Go でプロセス間通信

Last updated at Posted at 2020-04-27

MS が https://github.com/Microsoft/go-winio を公開しているので、これを使う。
以下がサンプル

server.go
import (
	"fmt"
	"io/ioutil"

	"github.com/Microsoft/go-winio"
)

func main() {
	pipeConfig := winio.PipeConfig{
		SecurityDescriptor: "S:(ML;;NW;;;LW)D:(A;;0x12019f;;;WD)", // SDDL Everyone
		InputBufferSize:    4096,
		OutputBufferSize:   4096,
	}

	listener, _ := winio.ListenPipe(`\\.\pipe\my-named-pipe`, &pipeConfig)
	defer listener.Close()

	for {
		conn, _ := listener.Accept()
		defer conn.Close()

		bytes, _ := ioutil.ReadAll(conn)
		fmt.Println(string(bytes))
	}
}
client.go
import (
	"github.com/Microsoft/go-winio"
)

func main() {
	conn, err := winio.DialPipe(`\\.\pipe\my-named-pipe`, nil)

	if conn != nil && err == nil {
		defer conn.Close()

		conn.Write([]byte("Hello, world!"))
	}
}
