xcbpolysegment(3) XCB Requests xcbpolysegment(3)

NAME
       xcbpolysegment - draw lines

SYNOPSIS
       #include 

   Request function
       xcbvoidcookiet xcbpolysegment(xcbconnectiont *conn,
              xcbdrawablet drawable, xcbgcontextt gc,
              uint32t segmentslen, const xcbsegmentt *segments);

REQUEST ARGUMENTS
       conn      The XCB connection to X11.

       drawable  A drawable (Window or Pixmap) to draw on.

       gc        The graphics context to use.

                 TODO: document which attributes of a gc are used

       segmentslen
                 The number of xcbsegmentt structures in segments.

       segments  An array of xcbsegmentt structures.

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 xcbsegmentt 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 multi‐
       ple times.

       TODO: include the xcbsegmentt data structure

       TODO: an example

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

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