Lock a set of properties
int SDL_LockProperties(SDL_PropertiesID props);
|props||the properties to lock|
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
Obtain a multi-threaded lock for these properties. Other threads will wait while trying to lock these properties until they are unlocked. Properties must be unlocked before they are destroyed.
The lock is automatically taken when setting individual properties, this function is only needed when you want to set several properties atomically or want to guarantee that properties being queried aren't freed in another thread.
It is safe to call this function from any thread.
This function is available since SDL 3.0.0.
