# Synopsis

(macro) void gdx_AddApproxBreakPnt(long option, long break_pnt_ndx)

# Purpose

Adds a break point to the current GDX linear approximation workspace

# Description

Adds a break point to the linear approximation workspace. The break point is the indication where the previously added 3D linear approximation points should stop to indicate the end of a linear approximation segment. The break_pnt_ndx is the 3D linear approximation point count at which a new linear approximation segment should start. No error checking is performed and it is assumed that a workspace is currently allocated and the GDX 3D linear approximation points have been added.

# Input

## option

Not used

## break_pnt_ndx

The index at which the GDX 3D linear approximation points start a new segment
