NAME
       MPI_Errhandler_free  - Frees an MPI-style error handler.

SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Errhandler_free(MPI_Errhandler *errhandler)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_ERRHANDLER_FREE(ERRHANDLER, IERROR)
	    INTEGER   ERRHANDLER, IERROR

C++ Syntax
       #include <mpi.h>
       void Errhandler::Free()

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.

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. By default, this error handler aborts the MPI job, except  for
       I/O  function  errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be
       used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
