overlapped winsock

my procedure has been trapped in a WSA_IO_INCOMPLETE vortex.according to msdn
/********************************************
WSA_IO_INCOMPLETE
(OS dependent)
Overlapped I/O event object not in signaled state.
The application has tried to determine the status of an overlapped operation which is not yet completed. Applications that use WSAGetOverlappedResult (with the fWait flag set to false) in a polling mode to determine when an overlapped operation has completed will get this error code until the operation is complete.
/*********************************************

when API WSAGetOverlappedResult () returns WSA_IO_INCOMPLETE i'd let my procedure continue to wait until tht overlapped IO be completed coz
msdn literally implys WSA_IO_INCOMPLETE ='you'd wait ' but once this thing received by my procedure. this 'not yet completed IO ' will never be completed.WsaGetLastError() returns WSA_IO_INCOMPLETE constantly/endlessly OOPS

why WSA_IO_INCOMPLETE occurs & this overlapped IO wouldn't be completed. show me a way out plz thank you!
