Create a new mutex.
void); SDL_Mutex* SDL_CreateMutex(
Returns the initialized and unlocked mutex or NULL on failure; call SDL_GetError() for more information.
All newly-created mutexes begin in the unlocked state.
Calls to SDL_LockMutex() will not return while the mutex is locked by another thread. See SDL_TryLockMutex() to attempt to lock without blocking.
SDL mutexes are reentrant.
This function is available since SDL 3.0.0.

/* Do stuff while mutex is locked */
