How to make a variadic macro (variable number of arguments)

I want to write a macro in C that accepts any number of parameters, not a specific number

example:

#define macro( X )  something_complicated( whatever( X ) )

where X is any number of parameters

I need this because whatever is overloaded and can be called with 2 or 4 parameters.

I tried defining the macro twice, but the second definition overwrote the first one!

The compiler I'm working with is g++ (more specifically, mingw)

Solution

  • C99 way:

    #define FOO(...) printf(__VA_ARGS__)
