Hello, 

You can use the Constrained_delaunay_triangulation_2 class,  here is an example:

I want to use CGAL lib in C++ to triangulate a polygonal domain as follows,
<http://cgal-discuss.949826.n4.nabble.com/file/t376283/RORHq.jpg>
The red line segments should not be split but the black can be split.

What kind of function should I use ? Can you raise a C++ example?
