# Synopsis

(macro) long gdx_GetNumOfApproxPnts()

# Purpose

Get the current GDX number of linear approximation points.

# Description

This function gets the current GDX number of linear approximation points that have been generated in the GDX linear approximation workspace. The value returned indicates the amount of linear approximation data values that will can be accessed from the application (see gdx__MoveApprox3DPnts for accessing the point data)

# Return

Number of linear approximation points
