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. --- keen.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'keen.c') diff --git a/keen.c b/keen.c index fdaae32..a3fbb74 100644 --- a/keen.c +++ b/keen.c @@ -1616,7 +1616,7 @@ static char *interpret_move(const game_state *state, game_ui *ui, ui->hpencil = 0; } ui->hcursor = 0; - return ""; /* UI activity occurred */ + return UI_UPDATE; } if (button == RIGHT_BUTTON) { /* @@ -1636,19 +1636,19 @@ static char *interpret_move(const game_state *state, game_ui *ui, ui->hshow = 0; } ui->hcursor = 0; - return ""; /* UI activity occurred */ + return UI_UPDATE; } } if (IS_CURSOR_MOVE(button)) { move_cursor(button, &ui->hx, &ui->hy, w, w, 0); ui->hshow = ui->hcursor = 1; - return ""; + return UI_UPDATE; } if (ui->hshow && (button == CURSOR_SELECT)) { ui->hpencil = 1 - ui->hpencil; ui->hcursor = 1; - return ""; + return UI_UPDATE; } if (ui->hshow && -- cgit v1.1
