xcb_image_text_16(3)		  XCB Requests		    xcb_image_text_16(3)

NAME
     xcb_image_text_16 - Draws text

SYNOPSIS
     #include <xcb/xproto.h>

   Request function
     xcb_void_cookie_t		       xcb_image_text_16(xcb_connection_t *conn,
	    uint8_t string_len,   xcb_drawable_t drawable,    xcb_gcontext_t gc,
	    int16_t x, int16_t y, const xcb_char2b_t *string);

REQUEST ARGUMENTS
     conn      The XCB connection to X11.

     string_lenThe  length of the string in characters. Note that this parameter
	       limited by 255 due to using 8 bits!

     drawable  The drawable (Window or Pixmap) to draw text on.

     gc        The graphics context to use.

	       The following graphics context components are  used:  plane-mask,
	       foreground,   background,  font,  subwindow-mode,  clip-x-origin,
	       clip-y-origin, and clip-mask.

     x	       The x coordinate of the first character, relative to  the  origin
	       of drawable.

     y	       The  y  coordinate of the first character, relative to the origin
	       of drawable.

     string    The string to draw. Only the first 255  characters  are	relevant
	       due  to the data type of string_len. Every character uses 2 bytes
	       (hence the 16 in this request's name).

DESCRIPTION
     Fills the destination rectangle with the background  pixel  from  gc,  then
     paints the text with the foreground pixel from gc. The upper-left corner of
     the  filled  rectangle  is  at  [x, y - font-ascent]. The width is overall-
     width, the height is font-ascent + font-descent. The  overall-width,  font-
     ascent and font-descent are as returned by xcb_query_text_extents (TODO).

     Note  that  using X core fonts is deprecated (but still supported) in favor
     of client-side rendering using Xft.

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_image_text_16_checked. See xcb-requests(3) for details.

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

     xcb_g_context_error_t
	       The specified graphics context does not exist.

     xcb_match_error_t
	       TODO: reasons?
