#define SDL_VERSION | ( | x | ) |
Macro to determine SDL version program was compiled against.
This macro fills in a SDL_version structure with the version of the library you compiled against. This is determined by what header the compiler uses. Note that if you dynamically linked the library, you might have a slightly newer or older version at runtime. That version can be determined with SDL_GetVersion(), which, unlike SDL_VERSION(), is not a macro.
x | A pointer to a SDL_version struct to initialize. |

#define SDL_VERSION_ATLEAST | ( | X, | |
Y, | |||
Z | |||
) | (SDL_COMPILEDVERSION >= SDL_VERSIONNUM(X, Y, Z)) |
This macro will evaluate to true if compiled with SDL at least X.Y.Z.
Definition at line 106 of file SDL_version.h.
#define SDL_VERSIONNUM | ( | X, | |
Y, | |||
Z | |||
) | ((X)*1000 + (Y)*100 + (Z)) |
This macro turns the version numbers into a numeric value:
(1,2,3) -> (1203)
This assumes that there will never be more than 100 patchlevels.
Definition at line 94 of file SDL_version.h.
const char* SDL_GetRevision | ( | void | ) |
Get the code revision of SDL that is linked against your program.
Returns an arbitrary string (a hash value) uniquely identifying the exact revision of the SDL library in use, and is only useful in comparing against other revisions. It is NOT an incrementing number.
Definition at line 381 of file SDL.c.
References SDL_REVISION.
int SDL_GetRevisionNumber | ( | void | ) |
Get the revision number of SDL that is linked against your program.
Returns a number uniquely identifying the exact revision of the SDL library in use. It is an incrementing number based on commits to hg.libsdl.org.
Definition at line 388 of file SDL.c.
References SDL_REVISION_NUMBER.
void SDL_GetVersion | ( | SDL_version * | ver | ) |
Get the version of SDL that is linked against your program.
If you are linking to SDL dynamically, then it is possible that the current version will be different than the version you compiled against. This function returns the current version, while SDL_VERSION() is a macro that tells you what version you compiled with.
This function may be called safely at any time, even before SDL_Init().
