# CGPathAddLines

Appends an array of new line segments to a mutable graphics path.

```
extern void CGPathAddLines(CGMutablePathRef path, const CGAffineTransform *m, const CGPoint *points, size_t count);
```

## Parameters

`path`

The mutable path to change.

`m`

A pointer to an affine transformation matrix, or `NULL` if no transformation is needed. If specified, Core Graphics applies the transformation to the lines before adding them to the path.

`points`

An array of points that specifies the line segments to add.

`count`

The number of elements in the array.

## Discussion

This is a convenience function that adds a sequence of connected line segments to a path. This function is equivalent to calling the [`CGPathMoveToPoint`](/documentation/CoreGraphics/CGPathMoveToPoint) function to move to the starting point of the first line segment, then repeatedly calling the [`CGPathAddLineToPoint`](/documentation/CoreGraphics/CGPathAddLineToPoint) to append the sequence of line segments.
