The best place to look is the headers and the source.  (The source
really is quite readable).  Also check out gtk/testgtk.c in the source
tree.  In your case, you want to look at /usr/include/gdk/gdk.h which
includes:

 */
void gdk_draw_point  (GdkDrawable  *drawable,
        GdkGC        *gc,
        gint    x,
        gint    y);
void gdk_draw_line   (GdkDrawable  *drawable,
        GdkGC        *gc,
        gint    x1,
        gint    y1,
        gint    x2,
        gint    y2);

etc.

  /usr/include/gtk/gtkdrawingarea.h
