NAME
MPI_Cartdim_get - Retrieves Cartesian topology information associated with a communicator. SYNTAX
C Syntax #include <mpi.h> int MPI_Cartdim_get(MPI_Comm comm, int *ndims) Fortran Syntax INCLUDE 'mpif.h' MPI_CARTDIM_GET(COMM, NDIMS, IERROR) INTEGER COMM, NDIMS, IERROR C++ Syntax #include <mpi.h> int Cartcomm::Get_dim() const INPUT PARAMETER
comm Communicator with Cartesian structure (handle). OUTPUT PARAMETERS
ndims Number of dimensions of the Cartesian structure (integer). IERROR Fortran only: Error status (integer). DESCRIPTION
MPI_Cartdim_get returns the number of dimensions of the Cartesian structure. 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++ func- tions 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. SEE ALSO

NAME
MPI_Comm_get_errhandler - Retrieves error handler associated with a communicator. SYNTAX
C Syntax #include <mpi.h> int MPI_Comm_get_errhandler(MPI_Comm comm, MPI_Errhandler *errhandler) Fortran Syntax INCLUDE 'mpif.h' MPI_COMM_GET_ERRHANDLER(COMM, ERRHANDLER, IERROR) INTEGER COMM, ERRHANDLER, IERROR C++ Syntax #include <mpi.h> MPI::Errhandler MPI::Comm::Get_errhandler() const INPUT PARAMETER
comm Communicator (handle). OUTPUT PARAMETERS
errhandler New error handler for communicator (handle). IERROR Fortran only: Error status (integer). DESCRIPTION
MPI_Comm_get_errhandler retrieves the error handler currently associated with a communicator. This call is identical to MPI_Errhandler_get, the use of which is deprecated. ERRORS
