NAME

6       XDrawString, XDrawString16 - draw text characters
7

SYNTAX

9       int  XDrawString(Display  *display,  Drawable  d,  GC gc, int x, int y,
10              _Xconst char *string, int length);
11
12       int XDrawString16(Display *display, Drawable d, GC gc, int  x,  int  y,
13              _Xconst XChar2b *string, int length);
14

ARGUMENTS

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

DESCRIPTION

32       Each  character  image, as defined by the font in the GC, is treated as
33       an additional mask for a fill operation on the drawable.  The  drawable
34       is  modified  only  where  the  font character has a bit set to 1.  For
35       fonts defined with 2-byte matrix indexing and used with  XDrawString16,
36       each byte is used as a byte2 with a byte1 of zero.
37
38       Both  functions  use  these  GC components: function, plane-mask, fill-
39       style, font, subwindow-mode, clip-x-origin,  clip-y-origin,  and  clip-
40       mask.   They  also  use these GC mode-dependent components: foreground,
41       background, tile, stipple, tile-stipple-x-origin,  and  tile-stipple-y-
42       origin.
43
44       XDrawString and XDrawString16 can generate BadDrawable, BadGC, and Bad‐
45       Match errors.

DIAGNOSTICS

48       BadDrawable
49                 A value for a Drawable argument does not name a defined  Win‐
50                 dow or Pixmap.
51
52       BadGC     A value for a GContext argument does not name a defined GCon‐
53                 text.
54
55       BadMatch  An InputOnly window is used as a Drawable.
56
57       BadMatch  Some argument or pair of arguments has the correct  type  and
58                 range  but  fails  to match in some other way required by the
59                 request.
