From 9f9f9eaa096e6be8c1613014868e919d6991b188 Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Sun, 24 Apr 2022 19:24:47 -0700 Subject: *: s/void */til_setup_t */ This brings something resembling an actual type to the private objects returrned in *res_setup. Internally libtil/rototiller wants this to be a til_setup_t, and it's up to the private users of what's returned in *res_setup to embed this appropriately and either use container_of() or casting when simply embedded at the start to go between til_setup_t and their private containing struct. Everywhere *res_setup was previously allocated using calloc() is now using til_setup_new() with a free_func, which til_setup_new() will initialize appropriately. There's still some remaining work to do with the supplied free_func in some modules, where free() isn't quite appropriate. Setup freeing isn't actually being performed yet, but this sets the foundation for that to happen in a subsequent commit that cleans up the setup leaks. Many modules use a static default setup for when no setup has been provided. In those cases, the free_func would be NULL, which til_setup_new() refuses to do. When setup freeing actually starts happening, it'll simply skip freeing when til_setup_t.free_func is NULL. --- src/modules/stars/stars.c | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) (limited to 'src/modules/stars/stars.c') diff --git a/src/modules/stars/stars.c b/src/modules/stars/stars.c index d7093fe..150602a 100644 --- a/src/modules/stars/stars.c +++ b/src/modules/stars/stars.c @@ -35,6 +35,7 @@ typedef struct stars_context_t { } stars_context_t; typedef struct stars_setup_t { + til_setup_t til_setup; float rot_adj; } stars_setup_t; @@ -48,14 +49,14 @@ float get_random_unit_coord() { } -static void * stars_create_context(unsigned ticks, unsigned num_cpus, void *setup) +static void * stars_create_context(unsigned ticks, unsigned num_cpus, til_setup_t *setup) { stars_context_t *ctxt; float z; struct points* p_ptr = NULL; if (!setup) - setup = &stars_default_setup; + setup = &stars_default_setup.til_setup; ctxt = malloc(sizeof(stars_context_t)); if (!ctxt) @@ -211,7 +212,7 @@ static void stars_render_fragment(void *context, unsigned ticks, unsigned cpu, t ctxt->offset_y = tmp_y; } -int stars_setup(const til_settings_t *settings, til_setting_t **res_setting, const til_setting_desc_t **res_desc, void **res_setup) +int stars_setup(const til_settings_t *settings, til_setting_t **res_setting, const til_setting_desc_t **res_desc, til_setup_t **res_setup) { const char *rot_adj; const char *rot_adj_values[] = { @@ -243,13 +244,13 @@ int stars_setup(const til_settings_t *settings, til_setting_t **res_setting, con if (res_setup) { stars_setup_t *setup; - setup = calloc(1, sizeof(*setup)); + setup = til_setup_new(sizeof(*setup), (void(*)(til_setup_t *))free); if (!setup) return -ENOMEM; sscanf(rot_adj, "%f", &setup->rot_adj); - *res_setup = setup; + *res_setup = &setup->til_setup; } return 0; -- cgit v1.2.1
