:ref:`MPI_Errhandler_free` |mdash| Frees an MPI-style error handler.


SYNTAX
------


C Syntax
^^^^^^^^

.. code-block:: c

   #include <mpi.h>

   int MPI_Errhandler_free(MPI_Errhandler *errhandler)


Fortran Syntax
^^^^^^^^^^^^^^

.. code-block:: fortran

   USE MPI
   ! or the older form: INCLUDE 'mpif.h'
   MPI_ERRHANDLER_FREE(ERRHANDLER, IERROR)
   	INTEGER	ERRHANDLER, IERROR


Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^

.. code-block:: fortran

   USE mpi_f08
   MPI_Errhandler_free(errhandler, ierror)
   	TYPE(MPI_Errhandler), INTENT(INOUT) :: errhandler
   	INTEGER, OPTIONAL, INTENT(OUT) :: ierror


INPUT PARAMETER
---------------
* ``errhandler``: MPI error handler (handle). Set to MPI_ERRHANDLER_NULL on exit.

OUTPUT PARAMETER
----------------
* ``ierror``: Fortran only: Error status (integer).

DESCRIPTION

Marks the error handler associated with errhandler for deallocation and
sets errhandler to MPI_ERRHANDLER_NULL. The error handler will be
deallocated after all communicators associated with it have been
deallocated.
