MPI_File_create_errhandler(3OpenMPI)									      MPI_File_create_errhandler(3OpenMPI)

NAME

       MPI_File_create_errhandler  - Creates an MPI-style error handler that can be attached to a file.

SYNTAX

C Syntax
       #include <mpi.h>
       int MPI_File_create_errhandler(MPI_File_errhandler_fn *function,
	    MPI_Errhandler *errhandler)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_FILE_CREATE_ERRHANDLER(FUNCTION, ERRHANDLER, IERROR)
	    EXTERNAL  FUNCTION
	    INTEGER   ERRHANDLER, IERROR

C++ Syntax
       #include <mpi.h> static MPI::Errhandler	    MPI::File::Create_errhandler(MPI::File::Errhandler_fn*	function)

INPUT PARAMETER

       function  User-defined error handling procedure (function).

OUTPUT PARAMETERS

       errhandler
		 MPI error handler (handle).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       Registers  the  user  routine function for use as an MPI exception handler. Returns in errhandler a handle to the registered exception han-
       dler.

       In the C language, the user routine function should be a C function of type MPI_File_errhandler_fn, which is defined as

	   typedef void (MPI_File_errhandler_fn)(MPI_File *, int *,
	   ...);

       The first argument to function is the file in use. The second is the error code to be returned by the MPI routine that raised the error.

       In the Fortran language, the user routine should be of the form:

	   SUBROUTINE FILE_ERRHANDLER_FN(FILE, ERROR_CODE, ...)
	       INTEGER FILE, ERROR_CODE

       In C++, the user routine function should be of the form:

	   typedef void MPI::File::Errhandler_fn(MPI::File &, int *,
	   ...);

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.

NAME

       MPI_File_get_position - Returns the current position of the individual file pointer.

SYNTAX

       C Syntax
	   #include <mpi.h>
	   int MPI_File_get_position(MPI_File fh, MPI_Offset *offset)

       Fortran Syntax (see FORTRAN 77 NOTES)
	   INCLUDE 'mpif.h'
	   MPI_FILE_GET_POSITION(FH, OFFSET, IERROR)
		  INTEGER FH, IERROR
		  INTEGER(KIND=MPI_OFFSET_KIND) OFFSET

C++ Syntax
       #include <mpi.h>
       MPI::Offset MPI::File::Get_position() const

INPUT PARAMETER

       fh	 File handle (handle).

OUTPUT PARAMETERS

       offset	 Offset of the individual file pointer (integer).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_File_get_position  returns,	in offset, the current position of the individual file pointer in etype units relative to the current dis-
       placement and file type.

FORTRAN 77 NOTES
       The MPI standard prescribes portable Fortran syntax for the OFFSET argument only for Fortran 90. Sun FORTRAN 77 users may use the  non-por-
       table syntax

	    INTEGER*MPI_OFFSET_KIND OFFSET

       where MPI_ADDRESS_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.
