MPI_Initialized(3)							MPI							MPI_Initialized(3)

NAME

       MPI_Initialized -  Indicates whether MPI_Init has been called.

SYNOPSIS

       int MPI_Initialized( int *flag )

OUTPUT ARGUMENT

       flag   - Flag is true if MPI_Init or MPI_Init_thread has been called and false otherwise.

NOTES

NOTES FOR FORTRAN

       All  MPI  routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list.  ierr
       is an integer and has the same meaning as the return value of the routine in C.	In Fortran, MPI routines are subroutines, and are  invoked
       with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       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.

       MPI_SUCCESS
	      - No error; MPI routine completed successfully.

NAME

       MPI_Finalized -	Indicates whether MPI_Finalize has been called.

SYNOPSIS

       int MPI_Finalized( int *flag )

OUTPUT PARAMETER

       flag   - Flag is true if MPI_Finalize has been called and false otherwise.  (logical)

THREAD AND INTERRUPT SAFETY

       This  routine  is  both	thread- and interrupt-safe.  This means that this routine may safely be used by multiple threads and from within a
       signal handler.
