====Syntax of getlinesettings ==== 
 <code c>
#include <graphics.h>
void getlinesettings(struct linesettingstype *lineinfo);
  </code>


==== Description of getlinesettings ==== 
<code c>
getlinesettings fills a linesettingstype structure pointed to by lineinfo
with information about the current line style, pattern, and thickness.
The linesettingstype structure is defined in graphics.h as follows:
struct linesettingstype {
   int linestyle;
   unsigned upattern;
   int thickness;
};
linestyle specifies in which style subsequent lines will be drawn (such
as solid, dotted, centered, dashed). The enumeration line_styles, defined
in graphics.h, gives names to these operators:
NameValue  ==== Description of getlinesettings ==== 
<code c>
SOLID_LINE0  Solid line
DOTTED_LINE     1  Dotted line
CENTER_LINE     2  Centered line
DASHED_LINE     3  Dashed line
USERBIT_LINE  4  User-defined line style
thickness specifies whether the width of subsequent lines drawn will be
normal or thick.
Name     Value  ==== Description of getlinesettings ==== 
<code c>
NORM_WIDTH     1  1 pixel wide
THICK_WIDTH  3  3 pixels wide
