       MPI_T_finalize -  Finalize the MPI tool information interface


       int MPI_T_finalize(void)


       This   routine   may   be   called   as   often  as  the  corresponding
       MPI_T_init_thread() routine up  to  the  current  point  of  execution.
       Calling  it  more  times returns a corresponding error code. As long as
       the number of calls to MPI_T_finalize() is smaller than the  number  of
       calls  to MPI_T_init_thread() up to the current point of execution, the
       MPI tool information interface remains initialized  and  calls  to  its
       routines    are    permissible.     Further,    additional   calls   to
       MPI_T_init_thread() after one or more  calls  to  MPI_T_finalize()  are
       permissible.  Once  MPI_T_finalize() is called the same number of times
       as  the  routine  MPI_T_init_thread()  up  to  the  current  point   of
       execution, the MPI tool information interface is no longer initialized.
       The  interface  can   be   reinitialized   by   subsequent   calls   to

       At  the  end of the program execution, unless MPI_Abort() is called, an
       application must have called MPI_T_init_thread()  and  MPI_T_finalize()
       an equal number of times.


       This  routine  is  thread-safe.   This  means  that this routine may be
       safely used by multiple threads without the need for any  user-provided
       thread  locks.  However, the routine is not interrupt safe.  Typically,
       this is due to the use of memory allocation routines such as malloc  or
       other  non-MPICH  runtime  routines  that are themselves not interrupt-


       All MPI routines (except MPI_Wtime and  MPI_Wtick  )  return  an  error
       value;  C routines as the value of the function and Fortran routines in
       the last argument.  Before the value is returned, the current MPI error
       handler  is called.  By default, this error handler aborts the MPI job.
       The error handler may  be  changed  with  MPI_Comm_set_errhandler  (for
       communicators),     MPI_File_set_errhandler     (for     files),    and
       MPI_Win_set_errhandler  (for   RMA   windows).    The   MPI-1   routine
       MPI_Errhandler_set  may  be  used  but  its  use  is  deprecated.   The
       predefined error handler MPI_ERRORS_RETURN may be used to  cause  error
       values  to  be  returned.  Note that MPI does not guarentee that an MPI
       program can continue past an error; however, MPI  implementations  will
       attempt to continue whenever possible.

              - No error; MPI routine completed successfully.
              - The MPI tool information interface is not initialized.
