typedef int PK_EDGE_curve_dir_t;

Used in:

PK_EDGE_curve_direction_t

This datatype specifies the method for determining a curve direction from a
set of options that are related to an edge.

It has the values:

    PK_EDGE_curve_dir_none_c      No direction is set
    PK_EDGE_curve_dir_fin_c       Use the fin of an edge to determine
                                  curve direction
    PK_EDGE_curve_dir_vertex_c    Use the vertex of an edge to determine
                                  curve direction
    PK_EDGE_curve_dir_point_c     Use a point and direction to determine
                                  curve direction
