WebThe C preprocessor is the macro preprocessor for the C, Objective-C and C++ computer programming languages.The preprocessor provides the ability for the inclusion of header files, macro expansions, conditional compilation, and line control.. In many C implementations, it is a separate program invoked by the compiler as the first part of … The preprocessor maintains a context stack, implemented as alinked list of cpp_context structures, which together representthe macro expansion state at any one time. The structcpp_reader member variable contextpoints to the current topof this stack. The top normally holds the unexpanded replacement … See more The preprocessor stores macro expansions in tokenized form. Thissaves repeated lexing passes during expansion, at the cost of a smallincrease in memory consumption on average. The tokens are storedcontiguously in … See more As discussed above, cpplib needs a way of marking tokens asunexpandable. Since the tokens cpplib handles are read-only once theyhave been … See more The C standard states that, after any parameters have been replacedwith their possibly-expanded arguments, the replacement list … See more Function-like macros only expand when immediately followed by aparenthesis.
