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), but apps should _only_ `#include "SDL.h"`!

Syntax

#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 struct to initialize.

Remarks

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.

Code Examples

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);
