I think these should be @retval instead of @return ?

You missed converting this __FUNCTION__ to __func__.

Variables should be declared at the top of the function, and initialized
separately.

Should these DEBUG_INFO messages which appear to be warnings/errors use
DEBUG_WARN or DEBUG_ERROR, instead?
