Get the thread identifier for the current thread.
Returns the ID of the current thread.
This thread identifier is as reported by the underlying operating system. If SDL is running on a platform that does not support threads the return value will always be zero.
This function also returns a valid thread ID when called from the main thread.
This function is available since SDL 3.0.0.
SDL_threadID threadID; /* Retrieve our current thread identifier */ threadID = SDL_ThreadID();
