The header files in this folder are the latest, greatest Universal Interfaces from Apple (version 2.0a3). These interfaces were taken from ETO #16, soon to be released. At this time, there are no equivalent assembly language interfaces available. Apple's Developer Tools Group expects to provide the assembly language interfaces shortly. The file NewRoutineNames.dict can be used with the MPW tool Canon to systematically update your source files to the new naming conventions used in these headers. If you don't use MPW, you can still read this file to see what's changed in the header files.
