long CamModifiedTrapezoidal(long master_position,long

follower_position);

Adds a modified trapezoidal curve to the table. The profile of a

normalized modified trapezoidal curve is shown in Figure 2.6.

• The master_position argument defines the master position at the

end of the curve.

• The follower_position position argument defines the follower

position at the end of the curve.

Returns 0 if successful, or -1 if there was an error.

This function requires five free segments.
