This is an example of how to use the JoystickExMessageRead function along with the JoystickExMessageType structure.

/*
struct JoystickExMessageType {
  unsigned long Xpos;         // The x position
  unsigned long Ypos;         // The y position
  unsigned long Zpos;         // The z position
  unsigned long Rpos;         // The rudder/4th axis position
  unsigned long Upos;         // The 5th axis position
  unsigned long Vpos;         // The 6th axis position
  unsigned long Buttons;      // The button states
  unsigned long ButtonNumber; // The current button number pressed
  unsigned long POV;          // The point of view state
};

task main()
{
  JoystickExMessageType jemt;
  while (true)
  {
    ClearScreen();
    char result = JoystickExMessageRead(MAILBOX1, jemt);
    if (result == NO_ERR)
