Function SDL_CreateMutex 

pub unsafe extern "C" fn SDL_CreateMutex() -> *mut SDL_Mutex

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.

Return value

Returns the initialized and unlocked mutex or NULL on failure; call SDL_GetError() for more information.

Thread safety

It is safe to call this function from any thread.

Availability

This function is available since SDL 3.2.0.
