Different camera vendors use very different makernotes format, so there is no generic interface in LibRaw to get makernotes access.
Some of makernotes (lens, shooting info) is parsed and stored in imgdata.lens and imgdata.makernotes.
Again, many fields are vendor specific and you need to write some code to deal with this data.
