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 han-dle handle
       dle to the registered exception handler.

       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++ 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.
