The docs/nav for 0.11.0 and 1.0.0 include an examples page:
http://api.mongodb.org/cxx/legacy-0.11.0/examples.html
http://api.mongodb.org/cxx/legacy-1.0.0-rc0/examples.html

In both cases the "using" example is incomplete:
http://api.mongodb.org/cxx/legacy-1.0.0-rc0/_using-example.html

Not sure if that is a doxygen fail, but these pages aren't useful at the moment.
