From dde6c5e93e26f6706cd04745928ae9ad5dddfc9f Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Thu, 22 Feb 2018 16:40:20 -0800 Subject: fb,settings,drm_fb,sd_fb: const settings_t readers The fb_ops entrypoints and their descendants are purely readers of the settings, so constify their settings_t instances and the operative functions which only read settings. --- src/drm_fb.c | 4 ++-- src/fb.h | 4 ++-- src/sdl_fb.c | 4 ++-- src/settings.c | 6 +++--- src/settings.h | 6 +++--- 5 files changed, 12 insertions(+), 12 deletions(-) diff --git a/src/drm_fb.c b/src/drm_fb.c index 855fce1..6599d9d 100644 --- a/src/drm_fb.c +++ b/src/drm_fb.c @@ -262,7 +262,7 @@ static setting_desc_t * mode_desc_generator(void *setup_context) /* setup is called repeatedly as settings is constructed, until 0 is returned. */ /* a negative value is returned on error */ /* positive value indicates another setting is needed, described in next_setting */ -int drm_fb_setup(settings_t *settings, setting_desc_t **next_setting) +int drm_fb_setup(const settings_t *settings, setting_desc_t **next_setting) { drm_fb_setup_t context = {}; setting_desc_generator_t generators[] = { @@ -314,7 +314,7 @@ static drmModeModeInfo * lookup_mode(drmModeConnector *connector, const char *mo /* prepare the drm context for use with the supplied settings */ -void * drm_fb_init(settings_t *settings) +void * drm_fb_init(const settings_t *settings) { drm_fb_t *c; const char *dev; diff --git a/src/fb.h b/src/fb.h index 3f313b2..7743b82 100644 --- a/src/fb.h +++ b/src/fb.h @@ -30,8 +30,8 @@ typedef struct fb_page_t { /* Supply this struct to fb_new() with the appropriate context */ typedef struct fb_ops_t { - int (*setup)(settings_t *settings, setting_desc_t **next); - void * (*init)(settings_t *settings); + int (*setup)(const settings_t *settings, setting_desc_t **next); + void * (*init)(const settings_t *settings); void (*shutdown)(void *context); int (*acquire)(void *context, void *page); void (*release)(void *context); diff --git a/src/sdl_fb.c b/src/sdl_fb.c index 7047f4a..52cf556 100644 --- a/src/sdl_fb.c +++ b/src/sdl_fb.c @@ -21,14 +21,14 @@ struct sdl_fb_page_t { }; -int sdl_fb_setup(settings_t *settings, setting_desc_t **next_setting) +int sdl_fb_setup(const settings_t *settings, setting_desc_t **next_setting) { /* TODO: window size?
