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/swarm/swarm.c | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) (limited to 'src/modules/swarm') diff --git a/src/modules/swarm/swarm.c b/src/modules/swarm/swarm.c index e708082..0d70568 100644 --- a/src/modules/swarm/swarm.c +++ b/src/modules/swarm/swarm.c @@ -48,6 +48,7 @@ typedef enum swarm_draw_style_t { } swarm_draw_style_t; typedef struct swarm_setup_t { + til_setup_t til_setup; swarm_draw_style_t draw_style; } swarm_setup_t; @@ -178,12 +179,12 @@ static inline uint32_t color_to_uint32(v3f_t color) { } -static void * swarm_create_context(unsigned ticks, unsigned num_cpus, void *setup) +static void * swarm_create_context(unsigned ticks, unsigned num_cpus, til_setup_t *setup) { swarm_context_t *ctxt; if (!setup) - setup = &swarm_default_setup; + setup = &swarm_default_setup.til_setup; ctxt = calloc(1, sizeof(swarm_context_t) + sizeof(*(ctxt->boids)) * SWARM_SIZE); if (!ctxt) @@ -421,7 +422,7 @@ static void swarm_render_fragment(void *context, unsigned ticks, unsigned cpu, t } -static int swarm_setup(const til_settings_t *settings, til_setting_t **res_setting, const til_setting_desc_t **res_desc, void **res_setup) +static int swarm_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 *styles[] = { "points", @@ -448,7 +449,7 @@ static int swarm_setup(const til_settings_t *settings, til_setting_t **res_setti if (res_setup) { swarm_setup_t *setup; - setup = calloc(1, sizeof(*setup)); + setup = til_setup_new(sizeof(*setup), (void(*)(til_setup_t *))free); if (!setup) return -ENOMEM; @@ -457,7 +458,7 @@ static int swarm_setup(const til_settings_t *settings, til_setting_t **res_setti setup->draw_style = i; } - *res_setup = setup; + *res_setup = &setup->til_setup; } return 0; -- cgit v1.2.3
