I'm just guessing, but LockFileEx() and LOCKFILE_EXCLUSIVE_LOCK might do the trick: http://msdn2.microsoft.com/en-us/library/aa365203.aspx Unfortunately, the open and exclusive lock combination is not atomic. There's also this - CreateFileTransacted(): http://msdn2.microsoft.com/en-us/library/aa363859.aspx which has the argument: dwShareMode ... If this parameter is 0 (zero) and CreateFileTransacted succeeds, the object cannot be shared and cannot be opened again until the handle is closed. ... The sharing options remain in effect until you close the handle to an object. ____________________________________________________________________________________ Expecting?
