Example for a variable number of parameters function:

static cmd_export_t cmds[]={
    {"print", print_f_0, 0, 0, REQUEST_ROUTE},   // overload test
    {"print", print_f_1, 1, print_fixup_f_1, REQUEST_ROUTE},
    {"print", print_f_2, 2, print_fixup_f_2, REQUEST_ROUTE},
    {"print", (cmd_function)print_f_var, VAR_PARAM_NO, 0,  REQUEST_ROUTE},
     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    {0, 0, 0, 0, 0}
};

...

static int print_f_var(struct sip_msg* msg, int no, action_u_t* vals)
{
    int r;
    for (r=0; r<no; r++)
        printf("%s", vals[r].u.string);
    printf("\n");
    return 1;
}

You can have fixups too, I omitted them for simplicity.
