In C there's no such concept as an array of functions, but you can
declare (and use) an array of _pointers_ to functions:

    extern int f(void), g(void), h(void);
    extern int (*fa[])(void) = { f, g, h };
    int i, ret;

    for (i = 0; i < sizeof fa/sizeof fa[0]; i++)
        ret = (*fa[i])(); /* or ret = (fa[i])(); */
