void MPI::Datatype::Get_name(char* type_name, int& resultlen)
const
- type
- Data type whose name is to be returned (handle).
- type_name
- The name previously stored on the data type, or an
empty string if not such name exists (string).
- resultlen
- Length of returned
name (integer).
- IERROR
- Fortran only: Error status (integer).
MPI_Type_get_name
returns the printable identifier associated with an MPI data type.
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.
