6 XDrawString, XDrawString16 - draw text characters
7
9 int XDrawString(Display *display, Drawable d, GC gc, int x, int y, char
10 *string, int length);
11
12 int XDrawString16(Display *display, Drawable d, GC gc, int x, int y,
13 XChar2b *string, int length);
14
16 d Specifies the drawable.
17
18 display Specifies the connection to the X server.
19
20 gc Specifies the GC.
21
22 length Specifies the number of characters in the string argument.
23
24 string Specifies the character string.
25
26
27 x
28 y Specify the x and y coordinates, which are relative to the
29 origin of the specified drawable and define the origin of the
30 first character.
31
33 Each character image, as defined by the font in the GC, is treated as
34 an additional mask for a fill operation on the drawable. The drawable
35 is modified only where the font character has a bit set to 1. For
36 fonts defined with 2-byte matrix indexing and used with XDrawString16,
37 each byte is used as a byte2 with a byte1 of zero.
38
39 Both functions use these GC components: function, plane-mask, fill-
40 style, font, subwindow-mode, clip-x-origin, clip-y-origin, and clip-
41 mask. They also use these GC mode-dependent components: foreground,
42 background, tile, stipple, tile-stipple-x-origin, and tile-stipple-y-
43 origin.
44
45 XDrawString and XDrawString16 can generate BadDrawable, BadGC, and Bad‐
46 Match errors.
47
49 BadDrawable
50 A value for a Drawable argument does not name a defined Win‐
51 dow or Pixmap.
52
53 BadGC A value for a GContext argument does not name a defined GCon‐
54 text.
55
56 BadMatch An InputOnly window is used as a Drawable.
57
58 BadMatch Some argument or pair of arguments has the correct type and
59 range but fails to match in some other way required by the
60 request.
