Sorry, I may have misunderstood the initial problem. You were 
asking how to test if a point is inside a polygon. Now you are 
referring to two polygons. This sound different.

Iterating on segments of a polygon is not so difficult and is 
highly dependent of the data structure you use to represent 
points, segments and polygons.

This really looks like an assignment or a D learning exercise. 
What do you need this for ?
Do you have the data structures already defined ?
