Subtype Matches

Notice in the code for iterating through the attributes that slapi_attr_type_cmp() takes 2, the value assigned to SLAPI_TYPE_CMP_SUBTYPE, as its third argument. The argument forces a comparison of attribute subtypes, such as the locale of an attribute, in addition to attribute types. Refer to Part II, Directory Server Plug-In API Reference for details on plug-in API functions and their arguments.
