That is one solution I have used in the past, however mocking them 
required a lot less work - especially if the mocking framework generates 
all of the code for you.  My framework takes an XML definition of a 
function signature (which can its self be code generated from a header) 
and produces a class object with a rich set of static member functions 
for setting return values and setting up parameter checks.
