MPI_Op_free - Frees a user-defined combination function
       handle


SYNOPSIS

       C:

            #include <mpi.h>
            int MPI_Op_free( op )
            MPI_Op  *op;

       C++:

            #include <mpi.h>

            void Op::Free()

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            INTEGER op, ierror

            CALL MPI_OP_FREE(op, ierror)


STANDARDS

       This release implements the MPI 1.2 standard, as
       documented by the MPI Forum in the spring 1997 release of
       MPI:  A Message Passing Interface Standard.


DESCRIPTION

       The MPI_Op_free routine frees a user-defined combination
       function handle.  This routine accepts the following
       parameter:

       op     Specifies the operation. On exit, op is set to
              MPI_OP_NULL.  (handle)

       ierror Specifies the return code value for successful
              completion, which is in MPI_SUCCESS.  MPI_SUCCESS
              is defined in the mpif.h file.
