       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 MPI_T_init_thread().

       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-safe.


       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.
