NAME
     MPI_Group_free - Frees a group

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Group_free ( group )
          MPI_Group *group;


     C++:

          #include <mpi.h>

          void Group::Free()


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          INTEGER group, ierror

          CALL MPI_GROUP_FREE(group, 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_Group_free routine frees a group.  This routine accepts the
     following parameter:

     group     Specifies a group (handle)

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

NOTES
     On output, group is set to MPI_GROUP_NULL.
