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++ 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.
