al_draw_filled_polygon - Allegro 5 API

       Draw  a  filled,  simple  polygon.   Simple  means  it  does  not  have  to  be  convex  but  must not be
       self-overlapping.

       • vertices - Interleaved array of (x, y) vertex coordinates

       • vertex_count - Number of vertices in the array

       • color - Color of the filled polygon

       When the y-axis is facing downwards (the usual), the coordinates must be ordered anti-clockwise.
