Question

Given this macro:

#define SOME_MACRO(ret, f, args) \
    typedef ret (*some_func_##f) args; \
    static some_func_##f my_func_##f = NULL;

Please let me know the equivalent for:

SOME_MACRO(void,  myFunctionName, (int a));

Thanks.

You can use the -E flag of gcc to see how the macro is expanded:

typedef void (*some_func_myFunctionName) (int a); static some_func_myFunctionName my_func_myFunctionName = ((void *)0);;
