Hi all, After reading about VA_NARG
I tried to implement function overloading depending on number of arguments in C using macros. Now the problem is:
void hello1(char *s) { ... }
void hello2(char *s, char *t) { ... }
// PP_NARG(...) macro returns number of arguments :ref to link above
// does not work
#define hello(...) hello ## PP_NARG(__VA_ARGS__)
int main(void)
{
hello("hi"); // call hello1("hi");
hello("foo","bar"); // call hello2("foo","bar");
return 0;
}
I've read this from c-faq. But still could not get it to work...
