var (
    NameMutex = "Shamem"
    kernel    = syscall.NewLazyDLL("kernel32.dll")
)

const (
    IPC_RMID   = 0
    IPC_CREAT  = 00001000
    IPC_EXCL   = 00002000
    IPC_NOWAIT = 00004000
)

func Lock_windows(Name string) (uintptr,bool) {
    id,_,err := kernel.NewProc("CreateMutexA").Call(0, 1,uintptr(unsafe.Pointer(&NameMutex)))
    if err.Error() != "The operation completed successfully" {
        return 0,false
    }
    return id,true
}

func UnLock_windows(id uintptr) {
    syscall.CloseHandle(syscall.Handle(id))
}

下面是linux系统上面的实现用的是使用共享内存的方法
func Lock_linux(Name string) (uintptr,err := syscall.Syscall6(syscall.SYS_SHMGET,uintptr(unsafe.Pointer(&NameMutex)),IPC_CREAT|IPC_EXCL, 0, 0)
    if err.Error() != "errno 0" {
        return 0,true
}

func UnLock_linux(id uintptr) {
    syscall.Syscall6(syscall.SYS_SHMCTL,id,IPC_RMID, 0)
}
