# Synopsis

PDX_MSGT gdx_CheckCurveDegenerate(long option, MDA_PTR cur, double tol, PDX_BOOL *degen)

# Purpose

Check if a GDX curve is degenerate.

# Description

This routine determines whether or not a curve is degenerate, to within a user-specified tolerance.

# Input

## option

Not used.

## cur

The curve to be checked.

## tol

The tolerance to use. The curve is considered to be degenerate if the diagonal of its minmax box is less than or equal to this tolerance.

# Output

## degen

Boolean flag indicating degeneracy: PDX_TRUE = degenerate. PDX_FALSE = not degenerate.

# Return

          Low level error return
