To define a variadic macro, define a macro with arguments where the last argument is three periods. Pre-processor processes the macros at compile time hence that macros replace with the corresponding code fragments.

Macro invocations appearing in that expansion are left unchanged. ![]() The macro and its parameters should be enclosed in parentheses. ![]() I'm trying to compile the demo matrix code from this lib. Some languages, such as C and C++, provide a way to define and invoke preprocessor. The C preprocessor is the macro preprocessor for several computer programming languages, such as C, Objective-C, C++, and a variety of Fortran languages. The analyzer has detected a potentially incorrect macro definition.
