[Boost-users] [wave] question about preprocessing hooks

20 Nov 2005

      Hello,

What is a correct way to implement 'defined_macro' hook? For some reason I 
always get empty 'definition' list.

My hook implementation looks like this:

class hook : public 
boost::wave::context_policies::default_preprocessing_hooks
{
public:
template <typename TokenT, typename ParametersT, typename DefinitionT>
void defined_macro(TokenT const ¯o_name, bool is_functionlike, 
ParametersT const ¶meters, DefinitionT const &definition, bool 
is_predefined)
{
    if (!definition.empty()) {
        // never gets here
    }
}
};

I am using Boost 1.33 and VC .NET 2005 compiler.
