SegFault because of calloc()

I've narrowed down a segfault I've been getting to the following code, but I don't know why it's happening.

My structs

Code:

---

/*Struct to store point*/
typedef struct{
  double x;
  double y;
}point;

/*Struct to store figures*/
typedef struct{
  char name[FIG_LEN +1];
  point* coords;
}figure;

---

The code at fault

Code:

---

  char line[LINE_LEN + 1];
  static figure* newFigure;
  int coord = 1;
  int numCoords = 2;

  newFigure->coords = calloc(numCoords, sizeof(point));

---

I get a segfault on the last line. I"m not sure if I'm accessing the structs in the correct way, is that the problem?

Thanks.

You are dereferencing a pointer that doesn't point to anything. What does newFigure point to?

To the line:

Code:

---

newFigure = calloc(1, sizeof(figure));

---

Which was not there...

Thank you

Post a more significant chunk of code then. More than likely you haven't posted the code that causes the segfault. You should also be checking the return value of calloc(), also why not use malloc() for "newFigure"?

Hey, sorry about that. When I said "was not there", I meant that I had forgotten to include it in my code, so it was the source of the error.

So I've found the error and am good now.
