# CGPathAddCurveToPoint

Appends a cubic Bézier curve to a mutable graphics path.

## Declaration

```occ
extern void CGPathAddCurveToPoint(CGMutablePathRef path, const CGAffineTransform *m, CGFloat cp1x, CGFloat cp1y, CGFloat cp2x, CGFloat cp2y, CGFloat x, CGFloat y);
```

## Parameters

- `path`: The mutable path to change. The path must not be empty.
- `m`: A pointer to an affine transformation matrix, or NULL if no transformation is needed. If specified, Core Graphics applies the transformation to the curve before it is added to the path.
- `cp1x`: The x-coordinate of the first control point.
- `cp1y`: The y-coordinate of the first control point.
- `cp2x`: The x-coordinate of the second control point.
- `cp2y`: The y-coordinate of the second control point.
- `x`: The x-coordinate of the end point of the curve.
- `y`: The y-coordinate of the end point of the curve.

## Discussion

Discussion Appends a cubic Bézier curve from the current point in a path to the specified location using two control points, after an optional transformation. Before returning, this function updates the current point to the specified location (x,y).
