The only routines that are callable by 68K clients running emulated on PPC machines are those defined in "OpenTransport.h", "OpenTptAppleTalk.h" and "OpenTptInternet.h". All routines defined in all other header files (specifically those in "OpenTptClient.h" and "OpenTptCommon.h") are available only to PPC-native clients on PPC machines, or 68K clients on 68K machines.
In addition, non-application code (such as OT modules, drivers, port scanner and configurators) will only run under the native architecture. For example, it's not possible to compile an OT driver as 68K code and have it run on a PPC.
In general, we recommend that you build all your Open Transport application code fat, both to run as quickly as possible and to guarantee future compatibility (see Technical Q&A NW 40).
