From the original Amiga UNIX 2.1 manual. Some things it mentions may not be in this release.

NAME

XDrawString, XDrawString16 - draw text characters

SYNTAX

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

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

ARGUMENTS

d Specifies the drawable.

display Specifies the connection to the XWIN 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 rela-
          tive 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.
