XDrawString(3)


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.

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

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
   BadMatch errors.

DIAGNOSTICS

   BadDrawable
             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.
