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.
