Create a new mutex.
Defined in <SDL3/SDL_mutex.h>
void); SDL_Mutex * SDL_CreateMutex(
(SDL_Mutex *) Returns the initialized and unlocked mutex or NULL on failure; call SDL_GetError() for more information.
All newly-created mutexes begin in the unlocked state.
Calls to SDL_LockMutex() will not return while the mutex is locked by another thread. See SDL_TryLockMutex() to attempt to lock without blocking.
SDL mutexes are reentrant.
This function is available since SDL 3.1.3.

mutex = SDL_CreateMutex();if (!mutex) {
"Couldn't create mutex\n");
SDL_LogError(SDL_LOG_CATEGORY_APPLICATION, return 1;
}
if (SDL_TryLockMutex(mutex) == 0) {
/* Do stuff while mutex is locked */
SDL_UnlockMutex(mutex);else {
} "Couldn't lock mutex\n");
SDL_LogError(SDL_LOG_CATEGORY_APPLICATION,
}
SDL_DestroyMutex(mutex);
