4 * Information the version of SDL in use.
6 * Represents the library's version as three levels: major revision
7 * (increments with massive changes, additions, and enhancements),
8 * minor revision (increments with backwards-compatible changes to the
9 * major revision), and patchlevel (increments with fixes to the minor

31 * Macro to determine SDL version program was compiled against.
33 * This macro fills in a SDL_version structure with the version of the
34 * library you compiled against. This is determined by what header the
35 * compiler uses. Note that if you dynamically linked the library, you might
36 * have a slightly newer or older version at runtime. That version can be
37 * determined with SDL_GetVersion(), which, unlike SDL_VERSION(),
40 * x A pointer to a SDL_version struct to initialize.
45 procedure SDL_VERSION(x: PSDL_Version);
48 * This macro turns the version numbers into a numeric value:
53 * This assumes that there will never be more than 100 patchlevels.

58 * This is the version number macro for the current SDL version.

68 * Get the version of SDL that is linked against your program.
70 * If you are linking to SDL dynamically, then it is possible that the
71 * current version will be different than the version you compiled against.
72 * This function returns the current version, while SDL_VERSION() is a
73 * macro that tells you what version you compiled with.

100 * Returns an arbitrary string (a hash value) uniquely identifying the
101 * exact revision of the SDL library in use, and is only useful in comparing
