From: Christian Heller Date: Tue, 30 Jul 2013 03:01:01 +0000 (+0200) Subject: Made the hierarchy between terminal screen, virtual screen, "pad", its frame etc... X-Git-Tag: tce~1106 X-Git-Url: https://plomlompom.com/repos/%7B%7B%20web_path%20%7D%7D/decks/%7B%7Bprefix%7D%7D/%7B%7Bdb.prefix%7D%7D/test.html?a=commitdiff_plain;h=349ca3893498469b4e002829d9a35da514d8b55d;p=plomrogue Made the hierarchy between terminal screen, virtual screen, "pad", its frame etc. more logic by renamings and comments. --- diff --git a/src/main.c b/src/main.c index b430925..2b16733 100644 --- a/src/main.c +++ b/src/main.c @@ -138,10 +138,11 @@ int main(int argc, char *argv[]) struct Win win_info = init_win(&win_meta, "Info", &world, draw_info_win);
