(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_UnlockMutex

Unlock the mutex.

Header File

Syntax

void SDL_UnlockMutex(SDL_Mutex *mutex);

Function Parameters

SDL_Mutex *

mutex

the mutex to unlock.

Remarks

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.

Version

This function is available since SDL 3.1.3.
