AW: How to cast a struct nl_object

[Joerg Pommnitz]

Sorry, I feel rather stupid now. struct nl_object is actually a public type 
defined
in netlink-types.h. I was confused by the fact that "struct nl_object" is not 
documented in the DocBook documentation on 
http://www.infradead.org/~tgr/libnl/doc-2.0
Please disregard my previous question.
