NAMEMPI_Finalized − Checks whether MPI_Finalize has completed.

---

SYNTAX

---

C Syntax#include <mpi.h> int MPI_Finalized(int *flag)

---

Fortran SyntaxINCLUDE 'mpif.h' MPI_FINALIZED(FLAG, IERROR) LOGICAL FLAG INTEGER IERROR

---

C++ Syntax#include <mpi.h> bool MPI::Is_finalized()

---

OUTPUT PARAMETERflag  True if MPI was finalized (logical). IERROR  Fortran only: Error status (integer).

---

DESCRIPTIONThis routine returns "true" if MPI_Finalize has completed. You can call MPI_Finalized before MPI_Init and after MPI_Finalize.

---

ERRORSAlmost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI::Exception object. Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error. 0
