31 cfa37a7b 2004-04-10 devnull .SH DESCRIPTION
32 cfa37a7b 2004-04-10 devnull These routines compute the geometrical extent of character strings when drawn on the display.  The most straightforward,
33 cfa37a7b 2004-04-10 devnull .BR stringsize ,
34 cfa37a7b 2004-04-10 devnull returns a
35 cfa37a7b 2004-04-10 devnull .B Point
36 cfa37a7b 2004-04-10 devnull representing the vector from upper left to lower right of the NUL-terminated string
37 cfa37a7b 2004-04-10 devnull .I s
38 cfa37a7b 2004-04-10 devnull drawn in font
39 cfa37a7b 2004-04-10 devnull .IR f .
40 cfa37a7b 2004-04-10 devnull .B Stringwidth
41 cfa37a7b 2004-04-10 devnull returns just the
42 cfa37a7b 2004-04-10 devnull .I x
43 cfa37a7b 2004-04-10 devnull component.
44 cfa37a7b 2004-04-10 devnull .B Stringnwidth
45 cfa37a7b 2004-04-10 devnull returns the width of the first
46 cfa37a7b 2004-04-10 devnull .I n
47 cfa37a7b 2004-04-10 devnull characters of
48 cfa37a7b 2004-04-10 devnull .IR s .

54 cfa37a7b 2004-04-10 devnull -encoded bytes.

67 cfa37a7b 2004-04-10 devnull .SH DIAGNOSTICS
68 cfa37a7b 2004-04-10 devnull Because strings are loaded dynamically, these routines may generate I/O
69 cfa37a7b 2004-04-10 devnull to the server and produce calls to the graphics error function.
