###### (This is the documentation for SDL3, which is the current stable version. [SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_ThreadID A unique numeric ID that identifies a thread. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_thread.h) ## Syntax ```c typedef Uint64 SDL_ThreadID; ``` ## Remarks These are different from [SDL_Thread](SDL_Thread) objects, which are generally what an application will operate on, but having a way to uniquely identify a thread can be useful at times. ## Version This datatype is available since SDL 3.1.3. ## See Also - [SDL_GetThreadID](SDL_GetThreadID) - [SDL_GetCurrentThreadID](SDL_GetCurrentThreadID) ---- [CategoryAPI](CategoryAPI), [CategoryAPIDatatype](CategoryAPIDatatype), [CategoryThread](CategoryThread)
