###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!) # SDL_GDKGetDefaultUser Gets a reference to the default user handle for GDK. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_system.h) ## Syntax ```c int SDL_GDKGetDefaultUser(XUserHandle * outUserHandle); ``` ## Function Parameters | | | | --------------------- | ------------------------------------------------------- | | **outUserHandle** | a pointer to be filled in with the default user handle. | ## Return Value Returns 0 if success, -1 if any error occurs. ## Remarks This is effectively a synchronous version of XUserAddAsync, which always prefers the default user and allows a sign-in UI. ## Version This function is available since SDL 3.0.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategorySystem](CategorySystem)
