    TITLE  :  fstream-File Pointer-DOS Handle Equivalency Table




  The  following  provides,   in  tabular  format,  the  equivalent
  functions between FILE pointers,  C++  file  Streams and DOS file
  handles.

  fstreams consist  of  fstreams,  ifstreams  and  ofstreams.  FILE
  pointers are  obtained  from  fopen,  freopen,  fdopen  and other
  functions. DOS  handles are obtained from open, _open, create and
  others.
