NAME

       MPI_File_get_view - Returns the process's view of data in the file.

SYNTAX

       C Syntax
           #include <mpi.h>
           int MPI_File_get_view(MPI_File fh, MPI_Offset *disp,
                  MPI_Datatype *etype, MPI_Datatype *filetype,
                     char *datarep)

       Fortran Syntax (see FORTRAN 77 NOTES)
           INCLUDE 'mpif.h'
           MPI_FILE_GET_VIEW(FH, DISP, ETYPE,
                   FILETYPE, DATAREP,  IERROR)
             INTEGER FH, ETYPE, FILETYPE, IERROR
             CHARACTER*(*) DATAREP
             INTEGER(KIND=MPI_OFFSET_KIND) DISP

C++ Syntax

       #include <mpi.h>
       void MPI::File::Get_view(MPI::Offset& disp,
            MPI::Datatype& etype,
            MPI::Datatype& filetype, char* datarep) const

INPUT PARAMETER

       fh        File handle (handle).

OUTPUT PARAMETERS

       disp      Displacement (integer).

       etype     Elementary data type (handle).

       filetype  File type (handle). See Restrictions, below.

       datarep   Data representation (string).

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       The MPI_File_get_view routine returns the process's view of the data in
       the file. The current values of the displacement, etype,  and  filetype
       are returned in disp, etype, and filetype, respectively.

       The  MPI_File_get_view  interface allows the user to pass a data-repre-
       sentation string via the datarep argument.

FORTRAN 77 NOTES

       The MPI standard prescribes portable Fortran syntax for the DISP  argu-
       ment  only  for  Fortran 90.  FORTRAN 77 users may use the non-portable
       syntax.

       tions  do  not  return  errors.  If the default error handler is set to
       MPI::ERRORS_THROW_EXCEPTIONS, 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   MPI_ERRORS_RETURN.   The   error   handler  may  be  changed  with
       MPI_File_set_errhandler;     the     predefined      error      handler
       MPI_ERRORS_ARE_FATAL  may  be  used to make I/O errors fatal. Note that
       MPI does not guarantee that an MPI program can continue past an  error.
