Arduino Uno Coding Help urgent!!!!!

I am using ATMega328p microcontroller, PORT B (0~7) & PORT D (8~13).

I need a code that blinks 2 LEDs on Port B at different rate and 2 LEDs on Port D at same rate using following lines:

1. void digitalWriteGeneric (unsigned char pin_number, unsigned char pin_setting);

2. int digitalReadGeneric (unsigned char pin_number);

3. void pinModeGeneric (unsigned char pin_number, unsigned char data_direction);

Thank you
