NAME¶
MPI_Finalized - Checks whether MPI has been finalized
C Syntax¶
#include <mpi.h>
int MPI_Finalized(int *flag)
Fortran Syntax¶
INCLUDE 'mpif.h'
MPI_FINALIZED(FLAG, IERROR)
LOGICAL FLAG
INTEGER IERROR
C++ Syntax¶
#include <mpi.h>
bool MPI::Is_finalized()
OUTPUT PARAMETER¶
- flag
- True if MPI was finalized, and false otherwise (logical).
- IERROR
- Fortran only: Error status (integer).
DESCRIPTION¶
This routine may be used to determine whether MPI has been finalized. It is one
of a small number of routines that may be called before MPI is initialized and
after MPI has been finalized (MPI_Initialized is another).
ERRORS¶
Almost 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.
