From: H.G. Muller Date: Wed, 18 Nov 2009 20:33:39 +0000 (-0800) Subject: refactoring evalgraph code X-Git-Tag: master-20091122~6 X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=cfe2d2d1940d9f17f3197cdcc36f4233150d3db1 refactoring evalgraph code This is the refactored EvalGraph code: the back-end part is separated off, and put in a file evalgraph.c, which in the future can also be used with XBoard. Only the WinBoard front-end code is left in the file wevalgraph.c. A new header file defines the variables and routines they share. --- diff --git a/evalgraph.c b/evalgraph.c new file mode 100644 index 0000000..9aa1fe7 --- /dev/null +++ b/evalgraph.c @@ -0,0 +1,336 @@ +/* + * evalgraph.c - Evaluation graph back-end part + * + * Author: Alessandro Scotti (Dec 2005) + * + * Copyright 2005 Alessandro Scotti + * + * ------------------------------------------------------------------------ + * + * GNU XBoard is free software: you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation, either version 3 of the License, or (at + * your option) any later version. + * + * GNU XBoard is distributed in the hope that it will be useful, but + * WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
