XDrawString(3)				  XLIB FUNCTIONS			   XDrawString(3)

       XDrawString, XDrawString16 - draw text characters

       int XDrawString(Display *display, Drawable d, GC gc, int x, int y, char *string, int

       int XDrawString16(Display *display, Drawable d, GC gc, int x, int y, XChar2b *string, int

       d	 Specifies the drawable.

       display	 Specifies the connection to the X server.

       gc	 Specifies the GC.

       length	 Specifies the number of characters in the string argument.

       string	 Specifies the character string.

       y	 Specify the x and y coordinates, which are relative to the origin of the speci-
		 fied drawable and define the origin of the first character.

       Each character image, as defined by the font in the GC, is treated as an additional mask
       for a fill operation on the drawable.  The drawable is modified only where the font char-
       acter has a bit set to 1.  For fonts defined with 2-byte matrix indexing and used with
       XDrawString16, each byte is used as a byte2 with a byte1 of zero.

       Both functions use these GC components: function, plane-mask, fill-style, font, subwindow-
       mode, clip-x-origin, clip-y-origin, and clip-mask.  They also use these GC mode-dependent
       components: foreground, background, tile, stipple, tile-stipple-x-origin, and tile-stip-

       XDrawString and XDrawString16 can generate BadDrawable, BadGC, and BadMatch errors.

		 A value for a Drawable argument does not name a defined Window or Pixmap.

       BadGC	 A value for a GContext argument does not name a defined GContext.

       BadMatch  An InputOnly window is used as a Drawable.

       BadMatch  Some argument or pair of arguments has the correct type and range but fails to
		 match in some other way required by the request.
