MPI_Type_delete_attr_function callback function

MPI_Type_delete_attr_function is a placeholder for the application-defined function name.

Syntax

int MPI_Type_delete_attr_function(
           MPI_Datatype datatype,
           int          datatype_keyval,
  _In_     void         *attribute_val,
  _In_opt_ void         *extra_state
);

Parameters

• datatype
  Datatype.

• datatype_keyval
  Key value.

• attribute_val [in]
  Attribute value.

• extra_state [in, optional]
  Extra state.

Return value

If an attribute delete function returns something other than MPI_SUCCESS, then the call that caused it to be invoked (for example, MPI_Type_free), is erroneous.

        INTEGER(KIND=MPI_ADDRESS_KIND) ATTRIBUTE_VAL, EXTRA_STATE
