vews_build_view in Views 2.0?

I have not had any experience with 1.0 Views, but are you looking for: views_get_current_view();

See issue #249934: Get view arg data from header.

It is still views_get_view().

Again, knowing nothing of Views 1, I am assuming that views_build_view would create the needed output to display a view on a page.

In that case, here is an example taken from #259034: Passing number of items to display per page as arguments and tweaked.

  $v = views_get_view('viewname');
  $v->init_display('default');
  echo $v->execute_display();

1) Please, there is no need for the extra ! and ?s -- it reads like you're panicked or something, and if you're panicked while working with a beta whose API has changed a lot, you're in the wrong line of work.
