I don't think Vim does have an understanding of functions. It knows about { or } in the first column (the [[ and ][ motions which you're using in your mapping).

Also, your example mapping:

onoremap if :<C-U>normal! [[vi{<cr>

On your example text:

template <typename Stream>
void do_read( Stream& stream, std::vector<char>& buf )
{
boost::asio::async_read(
stream, boost::asio::buffer( buf ), boost::bind( read_handler ));

stream.get_io_service().reset();
stream.get_io_service().run();

std::cout << "done" << std::endl;
}

Only selects 7 lines, unless there is a space character after the opening {.

...I see why.

I have 'selection' set to "exclusive". If I change it to "inclusive" then I get 8 lines.

Looking at WHAT gets copied with yif leads me to the following solution:

onoremap if :<C-U>normal! [[vi{h<cr>

This will work if 'selection' is set to "inclusive". If "exclusive" then you need to leave off the h as you did before. If you want to make your mapping generic you'll probably need to use an <expr> mapping which checks the value of the 'selection' option.
