From eeb2db283de9115f7256fa4cc49597d63e06b0ab Mon Sep 17 00:00:00 2001 From: Simon Tatham Date: Sun, 1 Oct 2017 12:52:12 +0100 Subject: New name UI_UPDATE for interpret_move's return "". Now midend.c directly tests the returned pointer for equality to this value, instead of checking whether it's the empty string. A minor effect of this is that games may now return a dynamically allocated empty string from interpret_move() and treat it as just another legal move description. But I don't expect anyone to be perverse enough to actually do that! The main purpose is that it avoids returning a string literal from a function whose return type is a pointer to _non-const_ char, i.e. we are now one step closer to being able to make this code base clean under -Wwrite-strings. --- misc.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'misc.c') diff --git a/misc.c b/misc.c index c1a595f..b44f1b1 100644 --- a/misc.c +++ b/misc.c @@ -9,6 +9,8 @@ #include "puzzles.h" +char UI_UPDATE[] = ""; + void free_cfg(config_item *cfg) { config_item *i; -- cgit v1.1
