1.2 Objective-C data types

The Objective-C interface uses types in the same way as the LispWorks FLI, with a restricted set of FLI types being used to describe method arguments and results. Some types perform special conversions to hide the FLI details (see Special argument and result conversion and Special method argument and result conversion).
