The TextBreakLocatorRef type is reference to a private structure that contains data needed by ATSUI and the Unicode Utilities function UCFindTextBreak to form various kind of text breaks. ATSUI developers must create a text break locator reference to set the style run and text layout attributes identified by the tag constants kATSUStyleTextLocatorTag and kATSULineTextLocatorTag. For a description of these tag constants, see Style Run Attribute Tag Constants and Text Layout Attribute Tag Constants, respectively. You create a text break locator reference by calling the Unicode Utilities function UCCreateTextBreakLocator. The Unicode Utilities functions UCFindTextBreak and UCCreateTextBreakLocator are documented in Unicode Utilities Preliminary Documentation at the Mac OS 8 and 9 Developer Documentation web site:
