Detailed Description

Helper class for the TAO_Storable_Naming_Context.

Guard class for the TAO_Storable_Naming_Context. It opens a file for read/write and sets a lock on it. It then checks if the file has changed and re-reads it if it has.

The destructor insures that the lock gets released.

 How to use this class:
   File_Open_Lock_and_Check flck(this, name_len > 1 ? "r" : "rw");
     ACE_CHECK;
