#679 win32file.UnlockFileEx incorrect expects ints as arguments

[Michael Brown]

Similar to https://sourceforge.net/p/pywin32/bugs/561/, UnlockFileEx incorrectly is expecting ints as its arguments, rather than unsigned longs:

len = 4294967295L
win32file.LockFileEx(handle, 0, len, len, overlapvar)
win32file.UnlockFileEx(handle, len, len, overlapvar)
Traceback (most recent call last):
File "<interactive input="">", line 1, in <module>
OverflowError: Python int too large to convert to C long

Untested fix:

in win32/src/win32file.i:MyUnlockFileEx():

• if (!PyArg_ParseTuple(args, "OiiO:UnlockFileEx",
• if (!PyArg_ParseTuple(args, "OkkO:UnlockFileEx",
