Error : illegal implicit conversion from 'OpaqueOTProcessProcPtr *' to
'pascal void (*)(void *)'

However, I can't find any header which defines OpaqueOTProcessProcPtr. How do I properly declare myDeferredUPP?

The type "OpaqueOTProcessProcPtr" is being generated by the macro TVECTOR_UPP_TYPE in "ConditionalMacros.h". The declaration of OpaqueOTProcessProcPtr is therefore "really" in OpenTransport.h, even though it wouldn't show up with a Find command.

The reason the error occurs is that "OTProcessUPP" is not the same type as "OTProcessProcPtr", and NewOTProcessUPP() returns the former. The call you intend to make is as follows:

OTProcessUPP myDeferredUPP = NewOTProcessUPP(MyDeferredMethod);
