#include <SDL3/SDL_mutex.h>

void SDL_DestroyRWLock(SDL_RWLock *rwlock);

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.

rwlock

the rwlock to destroy.

This function is available since SDL 3.2.0.
