XDrawString, XDrawString16
- draw text characters 
- 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);
 
- 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. 
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. 
- 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.
