Destroy a mutex created with SDL_CreateMutex().
Defined in <SDL3/SDL_mutex.h>
void SDL_DestroyMutex(SDL_Mutex *mutex);| SDL_Mutex * | mutex | the mutex to destroy. |
This function must be called on any mutex that is no longer needed. Failure to destroy a mutex will result in a system memory or resource leak. While it is safe to destroy a mutex that is unlocked, it is not safe to attempt to destroy a locked mutex, and may result in undefined behavior depending on the platform.
It is safe to call this function from any thread.
This function is available since SDL 3.2.0.
