Chapter 13
Function-Like Macros
Abstract
This chapter expands on the #define capability to show how it can be used to implement function-like macros. The reader will learn how macro parameters and arguments work at the preprocessor level.
Both the concatenation operator and stringize operator are covered in detail with examples. The newer macro variadic syntax is also covered, to show how variable parameter lists work with macros.
This chapter contains numerous examples to show how macros can be used to enhance embedded program functionality, maintainability, and readability.
Examples and exercises are for the popular PIC™ microcontroller manufactured by Microchip.
