Invalid handle value

[mgeisler]

I haven't tested this, but the

INVALID_HANDLE_VALUE = 0xFFFFFFFF

declaration in winapi.py line 54 might cause problems on x64 Python. In the Mercurial project we do it like this instead:

_HANDLE = ctypes.c_void_p
_INVALID_HANDLE_VALUE = _HANDLE(-1).value

using this as a monkey patch works for windows x64 py2.7 - without it fails complaining about invalid handle

...
from watchdog.utils import platform

# monkey
if platform.is_windows():
    import ctypes
    from watchdog.observers import winapi
    _HANDLE = ctypes.c_void_p
    _INVALID_HANDLE_VALUE = _HANDLE(-1).value

    winapi.INVALID_HANDLE_VALUE = _INVALID_HANDLE_VALUE
