# SDL_OpenXR_UnloadLibrary Unload the OpenXR loader previously loaded by [SDL_OpenXR_LoadLibrary](SDL_OpenXR_LoadLibrary). ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_openxr.h) ## Syntax ```c void SDL_OpenXR_UnloadLibrary(void); ``` ## Remarks SDL keeps a reference count of the OpenXR loader, calling this function will decrement that count. Once the reference count reaches zero, the library is unloaded. ## Thread Safety This function is not thread safe. ## Version This function is available since SDL 3.6.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryOpenxr](CategoryOpenxr)
