clear clipboard Error in clipboard_windows.go

[MangataTS]

problem

When I repeatedly read the clipboard and then clear the clipboard, the clipping operation fails and the content cannot be read.

solved

I guessed that the problem might be that I used the writeAll function and passed in an empty string, so I added a new function: clearAll

func clearAll() error {
    runtime.LockOSThread()
    defer runtime.UnlockOSThread()

    err := waitOpenClipboard()
    if err != nil {
        return err
    }

    r, _, err := emptyClipboard.Call(0)
    _, _, _ = closeClipboard.Call()
    if r == 0 {
        return err
    }
    return nil
}
