NAME

       XDrawString, XDrawString16 - draw text characters


SYNTAX

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

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


ARGUMENTS

       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.  and define the origin of the
                 first character

       x
       y         Specify the x and y coordinates, which are relative to the
                 origin of the specified drawable  .


DESCRIPTION

       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 character 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-stipple-y-
       origin.

       XDrawString and XDrawString16 can generate BadDrawable, BadGC, and Bad-
       Match errors.


DIAGNOSTICS

       BadDrawable
                 A value for a Drawable argument does not name a defined Win-
                 dow or Pixmap.

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

       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.
