I presume introspection is more portable.
I'm getting the error in forward1.hpp "cannot open include file:
'boost/introspection/detail/object_call_spec.hpp'". This file does not
appear to be on the sandbox.

Can I ask inside a template function if a member exists on a parameter of the function.
For example.
template <typename T> void func(T in) { exists(in, foo); }
Where the "exists" line would return true if "in" had a member "foo" otherwise false.
Note, however, that "introspection" libarary cannot detect an inherited member. If you use MSVC and don't need a portable code, you can use __if_exists statement: http://msdn.microsoft.com/en-us/library/x7wy9xh3(VS.80).aspx _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
