###### (This is the legacy documentation for SDL2, the previous stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current stable version.) # SDL_VERSION Macro to determine SDL version program was compiled against. ## Header File Defined in [SDL_version.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_version.h) ## Syntax ```c #define SDL_VERSION(x) \ { \ (x)->major = SDL_MAJOR_VERSION; \ (x)->minor = SDL_MINOR_VERSION; \ (x)->patch = SDL_PATCHLEVEL; \ } ``` ## Macro Parameters | | | | ----- | --------------------------------------------------------------- | | **x** | A pointer to a [SDL_version](SDL_version) struct to initialize. | ## Remarks This macro fills in a [SDL_version](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](SDL_GetVersion)(), which, unlike [SDL_VERSION](SDL_VERSION)(), is not a macro. ## Code Examples ```c SDL_version compiled; SDL_version linked; SDL_VERSION(&compiled); SDL_GetVersion(&linked); SDL_Log("We compiled against SDL version %u.%u.%u ...\n", compiled.major, compiled.minor, compiled.patch); SDL_Log("But we are linking against SDL version %u.%u.%u.\n", linked.major, linked.minor, linked.patch); ``` ## See Also - [SDL_version](SDL_version) - [SDL_GetVersion](SDL_GetVersion) ## (This is the legacy documentation for stable SDL2, the previous stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current stable version.) ## (This is the legacy documentation for stable SDL2, the current stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current development version.) ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryVersion](CategoryVersion)
