Type: laContext_PreprocessAssetsStateChangedCallback_FnPtr 

Callback pointer for when asset pre-processing is about to change state. Returning LA_FAILURE in the callback function during LA_CONTEXT_PREPROCESS_ASSETS_PENDING will suspend the preprocessing. Preprocess will not start until the function returns LA_SUCCESS.

typedef laResult (* laContext_PreprocessAssetsStateChangedCallback_FnPtr)(laContextPreprocessAssetsState);
