You can use boost::function to store the result of a boost::bind expression: http://boost.org/libs/bind/bind.html#with_boost_function For instance, you might write: boost::function bound = boost::bind(&A::f, _1); depending on the signature of A::f. Note, don't use 'new', just assign the value of boost::bind.

hi boost::bind( &A::f, _1 )

in different parts of my code. how can i define an alias for this expression?

Normally the easiest thing to do is to put it into a boost::function object. The correct type depends on the parameter to &A::f and the return type. Assuming that it is this: R A::f( B ) then something like this should work: boost::function< R ( B ) > do_f( boost::bind( &A::f, _1 ) ); R my_r = do_f( a_B ); K
