SDL_UnlockMutex - Man Page

#include <SDL3/SDL_mutex.h>

void SDL_UnlockMutex(SDL_Mutex *mutex);

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.

mutex

This function is available since SDL 3.2.0.
