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-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.
