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


 INPUT PARAMETER
 1i
fh
File handle (handle).

 OUTPUT PARAMETERS
 1i
disp
Displacement (integer).
 1i
etype
Elementary data type (handle).
 1i
filetype
File type (handle). See Restrictions, below.
 1i
datarep
Data representation (string).
 1i
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-representation string via the datarep argument.

 FORTRAN 77 NOTES
The MPI standard prescribes portable Fortran syntax for
the DISP argument only for Fortran 90. FORTRAN 77
users may use the non-portable syntax.
 INTEGER*MPI_OFFSET_KIND DISP

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

 ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions 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.
