Return a string result with out breaking loop

[Andrew]

Hi I have done this without error

:D

Yield returns the result I am looking for... however it does not 
continue looping. It does the same thing as return would

any suggestions

my code is as follows

serveraddr = ('', 8888)
srvr = ThreadingServer(serveraddr, SimpleXMLRPCRequestHandler, 
allow_none=True)

srvr.register_instance(theApp())

srvr.register_introspection_functions()

def watchos(path_to_watch="C:\\"):
     #get path or maintain current path of app
     FILE_LIST_DIRECTORY = 0x0001
     try: path_to_watch or "."
     except: path_to_watch = "."
     path_to_watch = os.path.abspath(path_to_watch)

     out1 = "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")
             out2 = str(full_filename) +  " " + str(theact)
         yield str(out2)

servg = watchos()
srvr.register_function(servg.next, 'watchos')

srvr.register_multicall_functions()
srvr.serve_forever()
