Unlock the mutex.

Header File

Defined in <SDL3/SDL_mutex.h>


void SDL_UnlockMutex(SDL_Mutex *mutex);

Function Parameters

SDL_Mutex * mutex the mutex to unlock.


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.


This function is available since SDL 3.0.0.
