Synopsis:
    #include <graph.h>
    short _FAR _wrapon( short wrap );

Description:
    The _wrapon function is used to control the display of text when the
    text output reaches the right side of the text window.  This is text
    displayed with the  _outtext and  _outmem functions.  The wrap argument
    can take one of the following values:

    _GWRAPON
        causes lines to wrap at the window border

    _GWRAPOFF
        causes lines to be truncated at the window border


Returns:
    The _wrapon function returns the previous setting for wrapping.

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

    main()
    {
        int i;
        char buf[ 80 ];

        _setvideomode( _TEXTC80 );
        _settextwindow( 5, 20, 20, 30 );
        _wrapon( _GWRAPOFF );
        for( i = 1; i <= 3; ++i ) {
            _settextposition( 2 * i, 1 );
            sprintf( buf, "Very very long line %d", i );
            _outtext( buf );
        }
        _wrapon( _GWRAPON );
        for( i = 4; i <= 6; ++i ) {
            _settextposition( 2 * i, 1 );
            sprintf( buf, "Very very long line %d", i );
            _outtext( buf );
        }
        getch();
        _setvideomode( _DEFAULTMODE );
    }
