Infinitive

[Cooklava]

1. I want to sing.
2. I want her to sing.


In #1, the infinitive is functioning as a noun (direct object. In #2, is the infinitive functioning as any part of speech? I know that "her" is its subject, but that's all. Is it only a bare infinitive in #2?

Thank you.

It's an objective complement.
