# CGPathAddLineToPoint

Appends a line segment to a mutable graphics path.

## Declaration

```occ
extern void CGPathAddLineToPoint(CGMutablePathRef path, const CGAffineTransform *m, 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 line before it is added to the path.
- `x`: The x-coordinate of the end point of the line.
- `y`: The y-coordinate of the end point of the line.

## Discussion

Discussion Before returning, this function updates the current point to the specified location (x,y).
