(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_GetVersion

Get the version of SDL that is linked against your program.

Header File

Syntax

int SDL_GetVersion(void);

Return Value

(int) Returns the version of the linked library.

Remarks

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 the version you compiled with.

This function may be called safely at any time, even before SDL_Init().

Version

This function is available since SDL 3.1.3.

Code Examples

const int compiled = SDL_VERSION;  /* hardcoded number from SDL headers */
const int linked = SDL_GetVersion();  /* reported by linked SDL library */

SDL_Log("We compiled against SDL version %d.%d.%d ...\n",
        SDL_VERSIONNUM_MAJOR(compiled),
        SDL_VERSIONNUM_MINOR(compiled),
        SDL_VERSIONNUM_MICRO(compiled));

SDL_Log("But we are linking against SDL version %d.%d.%d.\n",
        SDL_VERSIONNUM_MAJOR(linked),
        SDL_VERSIONNUM_MINOR(linked),
        SDL_VERSIONNUM_MICRO(linked));
