SYNTAX

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

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 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.
and can generate and errors.
DIAGNOSTICS
- A value for a Drawable argument does not name a defined Window or Pixmap.
- A value for a GContext argument does not name a defined GContext.
- An window is used as a Drawable.
- Some argument or pair of arguments has the correct type and range but fails to match in some other way required by the request.
