From b3243d75043cf1d70beb88d2a36eaebfe85c2c3f Mon Sep 17 00:00:00 2001 From: Simon Tatham Date: Sun, 1 Oct 2017 13:53:24 +0100 Subject: Return error messages as 'const char *', not 'char *'. They're never dynamically allocated, and are almost always string literals, so const is more appropriate. --- unfinished/slide.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'unfinished/slide.c') diff --git a/unfinished/slide.c b/unfinished/slide.c index 05a3f8b..9770013 100644 --- a/unfinished/slide.c +++ b/unfinished/slide.c @@ -273,7 +273,7 @@ static game_params *custom_params(const config_item *cfg) return ret; } -static char *validate_params(const game_params *params, int full) +static const char *validate_params(const game_params *params, int full) { if (params->w > MAXWID) return "Width must be at most " STR(MAXWID); @@ -886,7 +886,7 @@ static char *new_game_desc(const game_params *params, random_state *rs, return ret; } -static char *validate_desc(const game_params *params, const char *desc) +static const char *validate_desc(const game_params *params, const char *desc) { int w = params->w, h = params->h, wh = w*h; int *active, *link; @@ -1121,7 +1121,7 @@ static void free_game(game_state *state) } static char *solve_game(const game_state *state, const game_state *currstate, - const char *aux, char **error) + const char *aux, const char **error) { int *moves; int nmoves; -- cgit v1.1
