I neither found any explicit info about this in the manual nor on the forums. Code: /* works / #define TEST_MACRO(a,b) ((a)(b)) /* does not work compiler error: 'a' undeclared identifier / #define TEST_MACRO(a,b) \ ((a)(b))

I just wanted to test how well macros would be suited for doing some generic programming in lite-C without using void pointers. Something like this, for example: Code: // dynamic array of specific type #define CREATE_VECTOR(type) \ typedef struct VECTOR_##type { \ int size, count; \ type data; \ } VECTOR_##type ; Using void is ok for me in most cases. However, it gets impractical when dealing with primitive data types like int.
