Can I 'extend' a struct in C?

Question

typedef struct foo_s {
    int a;
} foo;

typedef struct bar_s {
    foo;
    int b;
} bar;

Essentially I want to do:

bar b;
b.a;
<

You can try using inheritance:

struct foo_s
{
    int a;
};

struct bar_s: foo_a
{
    int b;
};

Works in C++, not sure if it works in C.
