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_function *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_function*
            function)

DEPRECATED TYPE NAME NOTE

       MPI-2.2 deprecated the MPI_File_errhandler_fn and MPI::file::Errhandler_fn types in  favor
       of  MPI_File_errhandler_function  and  MPI::File::Errhandler_function, respectively.  Open
       MPI supports both names (indeed, the _fn names are typedefs to the _function names).

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 handler.

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

           typedef void (MPI_File_errhandler_function)(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_FUNCTION(FILE, ERROR_CODE, ...)
               INTEGER FILE, ERROR_CODE

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

           typedef void MPI::File::Errhandler_function(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++ 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.
