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

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_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.
