You can declare a macro in C99 that accepts a variable number of arguments.
The syntax for defining such a macro is similar to that of a function. For example:
#define debug(format, ...) fprintf (stderr, format, __VA_ARGS__) void Variadic_Macros_0() { debug ("a test string is printed out along with %x %x %x\n", 12, 14, 20); }
