[Boost-users] bimap find

Hi, I have one simple question for which I could not find answer in Bimap documentatio nor on the list. When searching bimap using find method what is the value of returned iterator if nothing matches search query? Example code: BimapDWORDVariant::right_map::const_iterator right_iter = bm.right.find(sSyncMsg); Thank you. BoskoM.
