Same as you'd for a single function pointer:

    int f(void); /* The function you want to point to */

    int (*pf)(void) = f; /* The function pointer */

    (*pf)(); /* Call the function through the function pointer */

So:

    int f(void), g(void), h(void); /* The three functions */

    int (*apf[3])(void) = { f, g, h };

    int i;

    for (i = 0; i < 3; i++)
        (*apf[i])(); /* Call each in a row */

Note that this is a general C question, and is not specific to DJGPP.
