# Synopsis

(macro) long gdx_GetNumOfApproxFacetEdges()

# Purpose

Get the current GDX number of linear approximation facet edges.

# Description

This function gets the current GDX number of linear approximation facet edges 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__MoveApproxFacetEdges for accessing the facet edge data)

# Return

Number of linear approximation points
