MPI_Type_get_name(3) 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++ 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.
