Synopsis:
    #include <graph.h>
    void _FAR _setlinestyle( unsigned short style );

Description:
    The _setlinestyle function sets the current line-style mask to the value
    of the style argument.

    The line-style mask determines the style by which lines and arcs are
    drawn.  The mask is treated as an array of 16 bits.  As a line is drawn,
    a pixel at a time, the bits in this array are cyclically tested.  When a
    bit in the array is 1, the pixel value for the current point is set
    using the current color according to the current plotting action;
    otherwise, the pixel value for the point is left unchanged.  A solid
    line would result from a value of 0xFFFF and a dashed line would result
    from a value of 0xF0F0

    The default line style mask is 0xFFFF

Returns:
    The _setlinestyle function does not return a value.

Example:
    #include <conio.h>
    #include <graph.h>

    #define DASHED 0xf0f0

    main()
    {
        unsigned old_style;

        _setvideomode( _VRES16COLOR );
        old_style = _getlinestyle();
        _setlinestyle( DASHED );
        _rectangle( _GBORDER, 100, 100, 540, 380 );
        _setlinestyle( old_style );
        getch();
        _setvideomode( _DEFAULTMODE );
    }
