From a58c1b216bb1d4547f7b2ef2703fe2d0cd3b5cac Mon Sep 17 00:00:00 2001 From: Simon Tatham Date: Sun, 1 Oct 2017 14:45:12 +0100 Subject: Make the code base clean under -Wwrite-strings. I've also added that warning option and -Werror to the build script, so that I'll find out if I break this property in future. --- grid.c | 15 ++++++++------- 1 file changed, 8 insertions(+), 7 deletions(-) (limited to 'grid.c') diff --git a/grid.c b/grid.c index 4929b5c..52648e5 100644 --- a/grid.c +++ b/grid.c @@ -1529,8 +1529,8 @@ static void grid_size_triangular(int width, int height, *yextent = height * vec_y; } -static char *grid_validate_desc_triangular(grid_type type, int width, - int height, const char *desc) +static const char *grid_validate_desc_triangular(grid_type type, int width, + int height, const char *desc) { /* * Triangular grids: an absent description is valid (indicating @@ -2855,8 +2855,9 @@ static char *grid_new_desc_penrose(grid_type type, int width, int height, random return dupstr(gd); } -static char *grid_validate_desc_penrose(grid_type type, int width, int height, - const char *desc) +static const char *grid_validate_desc_penrose(grid_type type, + int width, int height, + const char *desc) { int tilesize = PENROSE_TILESIZE, startsz, depth, xoff, yoff, aoff, inner_radius; double outer_radius; @@ -3032,8 +3033,8 @@ char *grid_new_desc(grid_type type, int width, int height, random_state *rs) } } -char *grid_validate_desc(grid_type type, int width, int height, - const char *desc) +const char *grid_validate_desc(grid_type type, int width, int height, + const char *desc) { if (type == GRID_PENROSE_P2 || type == GRID_PENROSE_P3) { return grid_validate_desc_penrose(type, width, height, desc); @@ -3048,7 +3049,7 @@ char *grid_validate_desc(grid_type type, int width, int height, grid *grid_new(grid_type type, int width, int height, const char *desc) { - char *err = grid_validate_desc(type, width, height, desc); + const char *err = grid_validate_desc(type, width, height, desc); if (err) assert(!"Invalid grid description."); return grid_news[type](width, height, desc); -- cgit v1.1
