''Example:'' The first version of SDL 2 was 2.0.0 : The version may also be reported as a 4-digit numeric value where the thousands place represents the major version, the hundreds place represents the minor version, and the tens and ones places represent the patchlevel (update version). ''Example:'' The first version number of SDL 2 was 2000 SDL_revision.h must be included in your program explicitly if you want to use the SDL_REVISION constant. == Structures == <> == Functions == <> * [[SDL_COMPILEDVERSION]] * [[SDL_GetRevision]] * [[SDL_GetRevisionNumber]] * [[SDL_GetVersion]] * [[SDL_REVISION]] * [[SDL_VERSION]] * [[SDL_version]] * [[SDL_VERSION_ATLEAST]] * [[SDL_VERSIONNUM]] ---- CategoryCategory
