Re: [Boost-users] [mpl] Using at_c within find_if

Hi there, I'm trying to find a solution for looking for type vector containing a specific type. On another thread I was suggested to use at_c within the find_if algorithm. Unfortunately the code doesn't compile.

Placeholder substitution won't work in templates taking non-type arguments, such as at_c.

typedef mpl::find_ifmpl::_1,1, int> >::type iter;

Try using 'at' and 'int_': typedef find_if >, int> >::type iter; Regards, Tobias
