Detailed Description

template<int N>
struct boost::proto::_child_c< N >

A PrimitiveTransform that returns N-th child of the current expression.

Example:

proto::terminal<int>::type i = {42};
proto::terminal<int>::type & j = proto::_child_c<0>()(-i);
assert( boost::addressof(i) == boost::addressof(j) );
