NAME

       xcb_poly_segment - draw lines

SYNOPSIS

       #include <xcb/xproto.h>

   Request function
       xcb_void_cookie_t xcb_poly_segment(xcb_connection_t *conn, xcb_drawable_t drawable, xcb_gcontext_t gc, uint32_t segments_len, const
	      xcb_segment_t *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

       segments_len
		 The number of xcb_segment_t structures in segments.

       segments  An array of xcb_segment_t 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 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

       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.

ERRORS

       xcb_drawable_error_t
		 The specified drawable does not exist.

       xcb_gc_error_t
		 The specified gc does not exist.

       xcb_match_error_t
		 TODO: reasons?

NAME

       xcb_create_gc - Creates a graphics context

SYNOPSIS

       #include <xcb/xproto.h>

   Request function
       xcb_void_cookie_t xcb_create_gc(xcb_connection_t *conn, xcb_gcontext_t cid, xcb_drawable_t drawable, uint32_t value_mask, const
	      uint32_t *value_list);

REQUEST ARGUMENTS

       conn	 The XCB connection to X11.

       cid	 The ID with which you will refer to the graphics context, created by xcb_generate_id.

       drawable  Drawable to get the root/depth from.

       value_mask
		 TODO: NOT YET DOCUMENTED.

       value_list
		 TODO: NOT YET DOCUMENTED.

DESCRIPTION

       Creates a graphics context. The graphics context can be used with any drawable that has the same root and depth as the specified drawable.

RETURN VALUE

       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_create_gc_checked. See xcb-requests(3) for details.

ERRORS

       xcb_pixmap_error_t
		 TODO: reasons?

       xcb_alloc_error_t
		 The X server could not allocate the requested resources (no memory?).

       xcb_value_error_t
		 TODO: reasons?

       xcb_drawable_error_t
		 The specified drawable (Window or Pixmap) does not exist.
