DESCRIPTION¶

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.

TODO: include the xcb_segment_t data structure

TODO: an example

RETURN VALUE¶

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