25 segments_len
26 The number of xcb_segment_t structures in segments.
27
28 segments An array of xcb_segment_t structures.

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

43 Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the
44 event loop.
45
46 If you want to handle errors directly with xcb_request_check instead,
47 use xcb_poly_segment_checked. See xcb-requests(3) for details.
