This GitHub wiki documents advanced C preprocessor techniques including pattern matching, token concatenation, and workarounds for expansion inhibition. It provides practical examples like the IIF macro that demonstrates how to properly handle conditional compilation. The content represents valuable knowledge for developers working with complex macro systems in C/C++.
Background
The C preprocessor is a macro processor used by C, C++, and related languages to transform code before compilation. Advanced preprocessor techniques enable metaprogramming capabilities but require understanding subtle behaviors like token concatenation and expansion rules.
