NAME
MPI_Type_get_name - Gets the name of a data type.
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Type_get_name(MPI_Datatype type, char *type_name,
int *resultlen)
Fortran Syntax
INCLUDE 'mpif.h'
TYPE_GET_NAME(TYPE, TYPE_NAME, RESULTLEN, IERROR)
INTEGER TYPE, RESULTLEN, IERROR
CHARACTER*(*) TYPE_NAME
C++ Syntax
#include <mpi.h>
void MPI::Datatype::Get_name(char* type_name, int& resultlen)
const
INPUT PARAMETER
type Data type whose name is to be returned (handle).
OUTPUT PARAMETERS
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).
DESCRIPTION
MPI_Type_get_name returns the printable identifier associated with an
MPI data type.
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.
