Unlock the read/write lock.
Defined in <SDL3/SDL_mutex.h>
void SDL_UnlockRWLock(SDL_RWLock *rwlock);| SDL_RWLock * | rwlock | the rwlock to unlock. |
Use this function to unlock the rwlock, whether it was locked for read-only or write operations.
It is legal for the owning thread to lock an already-locked read-only lock. 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 rwlock").
It is illegal to unlock a rwlock 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.
