MPI_Type_get_name - Gets the name of a data type.

#include <mpi.h>
int MPI_Type_get_name(MPI_Datatype type, char *type_name,
	int *resultlen)

USE MPI
! or the older form: INCLUDE 'mpif.h'
TYPE_GET_NAME(TYPE, TYPE_NAME, RESULTLEN, IERROR)
	INTEGER	TYPE, RESULTLEN, IERROR 
	CHARACTER*(*) TYPE_NAME

USE mpi_f08
MPI_Type_get_name(datatype, type_name, resultlen, ierror)
	TYPE(MPI_Datatype), INTENT(IN) :: datatype
	CHARACTER(LEN=MPI_MAX_OBJECT_NAME), INTENT(OUT) :: type_name
	INTEGER, INTENT(OUT) :: resultlen
	INTEGER, OPTIONAL, INTENT(OUT) :: ierror

#include <mpi.h>
void MPI::Datatype::Get_name(char* type_name, int& resultlen)
	const

Data type whose name is to be returned (handle).

The name previously stored on the data type, or an empty string if not such name exists (string).
Length of returned name (integer).
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.
