X Version 11                                      libxcb 1.17.0                              xcb_poly_segment(3)

       Draws  multiple,  unconnected lines. For each segment, a line is drawn between (x1, y1) and (x2, y2). The
       lines are drawn in the order listed in the array of xcb_segment_t structures and does not perform joining
       at coincident endpoints. For any given line, a pixel is not drawn more than once. If lines intersect, the
       intersecting pixels are drawn multiple times.

                 The number of xcb_segment_t structures in segments.

       segments  An array of xcb_segment_t structures.

       Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the event loop.

       If you want to handle errors directly with xcb_request_check instead, use  xcb_poly_segment_checked.  See
       xcb-requests(3) for details.
