In this chapter a number of more advanced examples have been presented to illustrate various features of the FLI. The use of the FLI to pass strings dynamically to Win32 API functions was examined, as was the definition of new FLI types and the use of callable functions and foreign functions, including code using blocks.
The next two chapters form the reference section of this manual. They provide reference entries for the functions, macros, and types which make up the FLI.
