INTEGER TYPE, RESULTLEN, IERROR
CHARACTER*(*) TYPE_NAME
18.2.399.1.3. Fortran 2008 Syntax
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
18.2.399.2. INPUT PARAMETER
type
: Data type whose name is to be returned (handle).
18.2.399.3. 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).
18.2.399.4. DESCRIPTION
MPI_Type_get_name returns the printable identifier associated with an MPI data type.
18.2.399.5. ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
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.
