Hi,
I tried to lock file in w2k using example directly from pyWin32 manual:
#--------------
>>> import pywintypes
>>> ov=pywintypes.OVERLAPPED() #used to indicate starting region to lock
>>> highbits=0xffff0000
>>> file="c:\\\\wilma.txt"
>>> import win32file
>>> import win32security
>>> import win32api
>>> secur_att = win32security.SECURITY_ATTRIBUTES()
>>> secur_att.Initialize()
>>> hfile=win32file.CreateFile( file, \
... win32con.GENERIC_READ|win32con.GENERIC_WRITE, \
... win32con.FILE_SHARE_READ|win32con.FILE_SHARE_WRITE, \
... secur_att, \
... win32con.OPEN_ALWAYS, \
... win32con.FILE_ATTRIBUTE_NORMAL , 0 )
>>> win32file.LockFileEx(hfile,win32con.LOCKFILE_EXCLUSIVE_LOCK,0,highbits,ov)
Traceback (most recent call last):
File "<interactive input>", line 1, in ?
OverflowError: long int too large to convert to int
#-------------
However, using highbits=0x7fff0000 # equals hex(sys.maxint) gives no errors, but does locking work if highbits are not exactly 0xffff0000?
Does anybody have example of locking the whole directory in one go without looping thru its files?
