ORC_DEBUG_WARNING	Messages at this level indicate something has occurred that a developer looking into an application problem may want to know.
ORC_DEBUG_INFO	Messages at this level provide high-level information about Orc internals.
ORC_DEBUG_DEBUG	The default level for logging messages.
ORC_DEBUG_LOG	The level for messages that probably don't need to be logged at all.

ORC_FUNCTION

#define ORC_FUNCTION __PRETTY_FUNCTION__

Internal macro that points to __PRETTY_FUNCTION__ or __func__ if the former is not available.
