65 * \brief Macro to determine SDL version program was compiled against.
67 * This macro fills in a SDL_version structure with the version of the
68 * library you compiled against. This is determined by what header the
69 * compiler uses. Note that if you dynamically linked the library, you might
70 * have a slightly newer or older version at runtime. That version can be
71 * determined with SDL_GetVersion(), which, unlike SDL_VERSION(),
74 * \param x A pointer to a SDL_version struct to initialize.

92 * This assumes that there will never be more than 100 patchlevels.

95 ((X)*1000 + (Y)*100 + (Z))

112 * If you are linking to SDL dynamically, then it is possible that the
113 * current version will be different than the version you compiled against.

115 * macro that tells you what version you compiled with.
