DESCRIPTION
       MPIFilegetsize  returns,  in size , the current size in bytes of the
       file associated with the file  handle  fh.  Note  that  the  file  size
       returned  by  Solaris  may not represent the number of bytes physically
       allocated for the file in those cases where all bytes in this file have
       not been written at least once.


FFOORRTTRRAANN 7777 NNOOTTEESS
       The  MPI standard prescribes portable Fortran syntax for the SIZE argu-
       ment only for Fortran 90. Sun FORTRAN 77 users may use the non-portable
       syntax

            INTEGER*MPIOFFSETKIND SIZE

       where  MPIADDRESSKIND  is  a constant defined in mpif.h and gives the
       length of the declared integer in bytes.


EERRRROORRSS
       Almost all MPI routines return an error value; C routines as the  value
       of  the  function  and Fortran routines in the last argument. C++ func-
       tions do not return errors. If the default  error  handler  is  set  to
       MPI::ERRORSTHROWEXCEPTIONS, then on error the C++ exception mechanism
       will be used to throw an MPI:Exception object.

       Before the error value is returned, the current MPI  error  handler  is
       called.  For  MPI I/O function errors, the default error handler is set
       to  MPIERRORSRETURN.  The  error  handler   may   be   changed   with
       MPIFileseterrhandler;      the      predefined     error     handler
       MPIERRORSAREFATAL may be used to make I/O errors  fatal.  Note  that
       MPI  does not guarantee that an MPI program can continue past an error.
