Wiring and "C" style code by BARRAGAN

Demonstrates how to mix "C" syntax code within a Wiring program. All C code should be enclosed in an extern "C" { } section

extern "C" {
   
  typedef int STEPPER_COORD;

  typedef struct _stepper_xy {
    STEPPER_COORD x;
    STEPPER_COORD y;
  } 
  STEPPER_POINT;
  
  void test(STEPPER_POINT *a){
    a->x = 50;
    a->y = 20;
  } 
  
}

STEPPER_POINT myPt;

void setup(){  
  Serial.begin(9600);
  myPt.x = 100;  // access the x and y components of
  myPt.y = 100;  // a variable type STEPPER_POINT
  Serial.print("myPt is: ");
  Serial.print(myPt.x, DEC);
  Serial.print(", ");
  Serial.println(myPt.y, DEC);
  test(&myPt);
  Serial.print("now myPt is: ");
  Serial.print(myPt.x, DEC);
  Serial.print(", ");
  Serial.println(myPt.y, DEC);
}

void loop()
{

}
