Unlock the mutex.
Defined in <SDL3/SDL_mutex.h>
void SDL_UnlockMutex(SDL_Mutex *mutex);| SDL_Mutex * | mutex | the mutex to unlock. |
It is legal for the owning thread to lock an already-locked mutex. It must unlock it the same number of times before it is actually made available for other threads in the system (this is known as a "recursive mutex").
It is illegal to unlock a mutex that has not been locked by the current thread, and doing so results in undefined behavior.
This function is available since SDL 3.2.0.
