我们从Python开源项目中，提取了以下3个代码示例，用于说明如何使用win32con.FILE_SHARE_WRITE。
def watchos(): #get path or maintain current path of app FILE_LIST_DIRECTORY = 0x0001 try: path_to_watch = myos.get() or "." except: path_to_watch = "." path_to_watch = os.path.abspath(path_to_watch) textbox.insert(END, "Watching %s at %s" % (path_to_watch, time.asctime()) + "\n\n") # FindFirstChangeNotification sets up a handle for watching # file changes. while 1: hDir = win32file.CreateFile ( path_to_watch, FILE_LIST_DIRECTORY, win32con.FILE_SHARE_READ | win32con.FILE_SHARE_WRITE, None, win32con.OPEN_EXISTING, win32con.FILE_FLAG_BACKUP_SEMANTICS, None ) change_handle = win32file.ReadDirectoryChangesW ( hDir, 1024, True,#Heap Size include_subdirectories, win32con.FILE_NOTIFY_CHANGE_FILE_NAME | win32con.FILE_NOTIFY_CHANGE_DIR_NAME | win32con.FILE_NOTIFY_CHANGE_ATTRIBUTES | win32con.FILE_NOTIFY_CHANGE_SIZE | win32con.FILE_NOTIFY_CHANGE_LAST_WRITE | win32con.FILE_NOTIFY_CHANGE_SECURITY, None, None ) # Loop forever, listing any file changes. The WaitFor... will # time out every half a second allowing for keyboard interrupts # to terminate the loop. ACTIONS = { 1 : "Created", 2 : "Deleted", 3 : "Updated", 4 : "Renamed from something", 5 : "Renamed to something" } results = change_handle for action, files in results: full_filename = os.path.join(path_to_watch, files) theact = ACTIONS.get(action, "Unknown") textbox.insert(END, str(full_filename) + "\t" + str(theact) +"\n")
def run(self): if running_on_linux()==True: print("thread: start") wm = pyinotify.WatchManager() print("wathcing path",self.watch_path) ret=wm.add_watch(self.watch_path, pyinotify.IN_CLOSE_WRITE, self.onChange,False,False) print(ret) print("thread: start notifyer",self.notifier) self.notifier = pyinotify.Notifier(wm) try: while 1: self.notifier.process_events() if self.notifier.check_events(): self.notifier.read_events() #self.notifier.loop() except: print("error in notify",sys.exc_info()[0]) else: hDir = win32file.CreateFile (self.watch_path,FILE_LIST_DIRECTORY,win32con.FILE_SHARE_READ | win32con.FILE_SHARE_WRITE | win32con.FILE_SHARE_DELETE,None,win32con.OPEN_EXISTING,win32con.FILE_FLAG_BACKUP_SEMANTICS,None) while 1: results = win32file.ReadDirectoryChangesW (hDir,1024,True, win32con.FILE_NOTIFY_CHANGE_FILE_NAME | win32con.FILE_NOTIFY_CHANGE_DIR_NAME | win32con.FILE_NOTIFY_CHANGE_ATTRIBUTES | win32con.FILE_NOTIFY_CHANGE_SIZE | win32con.FILE_NOTIFY_CHANGE_LAST_WRITE | win32con.FILE_NOTIFY_CHANGE_SECURITY, None, None) for action, file in results: full_filename = os.path.join (self.watch_path, file) self.onChange(full_filename)
