MPI_File_set_view(3)							MPI						      MPI_File_set_view(3)

NAME

       MPI_File_set_view -  Sets the file view

SYNOPSIS

       int MPI_File_set_view(MPI_File mpi_fh, MPI_Offset disp, MPI_Datatype etype,
			    MPI_Datatype filetype, char *datarep, MPI_Info info)

INPUT PARAMETERS

       fh     - file handle (handle)
       disp   - displacement (nonnegative integer)
       etype  - elementary datatype (handle)
       filetype
	      - filetype (handle)
       datarep
	      - data representation (string)
       info   - info object (handle)

NOTES FOR FORTRAN

       All  MPI  routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list.  ierr
       is an integer and has the same meaning as the return value of the routine in C.	In Fortran, MPI routines are subroutines, and are  invoked
       with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

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 file-
       type 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++ func-
       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.
