An experiment:
_________________________________
#include <stdio.h>


struct foo_0
{
      unsigned int blah0;
};

struct foo_1
{
      unsigned int blah0;
      unsigned int blah1;
};


void foo_0(struct foo_0* self, int a, int b)
{
      printf("foo_0(%p, blah0: %u, %u, %u)\n",
             (void*)self, self->blah0, a, b);
}

void foo_1(struct foo_1* self, int a, int b)
{
      printf("foo_1(%p, blah0: %u, blah1: %u, %u, %u)\n",
             (void*)self, self->blah0, self->blah1, a, b);
}


#define foo(a, ...) \
      (_Generic((a),   \
          struct foo_0*: foo_0, \
          struct foo_1*: foo_1 \
      )((a), __VA_ARGS__))


int main(void)
{
      struct foo_0 f0 = { 1 };
      struct foo_1 f1 = { 2, 3 };

      foo(&f0, 4, 5); // Calls foo_0
      foo(&f1, 4, 5); // Calls foo_1

      return 0;
}
_________________________________

foo seems pretty nice to me. :^)
