You can be forgiven for not looking in Quartz Display Services for this one. The function you're after is CGWarpMouseCursorPosition.

Since the documentation doesn't say, you'll have to experiment to determine which co-ordinate system it uses—i.e., where the origin is and which way positive y goes.
