al_draw_polyline(3)                                        al_draw_polyline(3)

NAME
       al_draw_polyline - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro_primitives.h>

              void al_draw_polyline(const float* vertices, int vertex_stride,
                 int vertex_count, int join_style, int cap_style,
                 ALLEGRO_COLOR color, float thickness, float miter_limit)


DESCRIPTION
       Draw a series of line segments.

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

       o vertex_stride - the number of bytes between pairs of vertices (the
         stride)

       o vertex_count - Number of vertices in the array

       o join_style - Member of ALLEGRO_LINE_JOIN(3) specifying how to render
         the joins between line segments

       o cap_style - Member of ALLEGRO_LINE_CAP(3) specifying how to render
         the end caps

       o color - Color of the line

       o thickness - Thickness of the line, pass <= 0 to draw hairline lines

       o miter_limit - Parameter for miter join style

       The stride is normally 2 * sizeof(float) but may be more if the vertex
       coordinates are in an array of some structure type, e.g.


              struct VertexInfo {
                 float x;
                 float y;
                 int id;
              };

              void my_draw(struct VertexInfo verts[], int vertex_count, ALLEGRO_COLOR c)
              {
                 al_draw_polyline((float *)verts, sizeof(VertexInfo), vertex_count,
                    ALLEGRO_LINE_JOIN_NONE, ALLEGRO_LINE_CAP_NONE, c, 1.0, 1.0);
              }


       The stride may also be negative if the vertices are stored in reverse
       order.
