SHM GET Example

package mainimport ("fmt""github.com/hslam/ftok""github.com/hslam/shm""time")funcmain() {key,err:=ftok.Ftok("/tmp",0x22)iferr!=nil {panic(err)}shmid,data,err:=shm.GetAttach(key,128,shm.IPC_CREAT|0600)iferr!=nil {panic(err)}defershm.Remove(shmid)defershm.Detach(data)context:= []byte("Hello World")copy(data,context)fmt.Println(string(data[:11]))time.Sleep(time.Second*10)}

package mainimport ("fmt""github.com/hslam/ftok""github.com/hslam/shm")funcmain() {key,err:=ftok.Ftok("/tmp",0x22)iferr!=nil {panic(err)}_,data,err:=shm.GetAttach(key,128,0600)iferr!=nil {panic(err)}defershm.Detach(data)fmt.Println(string(data[:11]))}

Output
