Destroy a read/write lock created with SDL_CreateRWLock().
Defined in <SDL3/SDL_mutex.h>
void SDL_DestroyRWLock(SDL_RWLock *rwlock);| SDL_RWLock * | rwlock | the rwlock to destroy. |
This function must be called on any read/write lock that is no longer needed. Failure to destroy a rwlock will result in a system memory or resource leak. While it is safe to destroy a rwlock that is unlocked, it is not safe to attempt to destroy a locked rwlock, and may result in undefined behavior depending on the platform.
This function is available since SDL 3.2.0.
