With Frama-C Nitrogen, Kernel_function.set_spec is what you need.

Note that the way of handling annotations will fully changed in the next 
major release. Hopefully it will be simple and more homogeneous for the 
different kind of annotations (function contracts, global annotations 
and code annotations).

Hope this helps,
