llRotLookAt() help ....

Hi,

Can someone give me a bit of help with llRotLookAt please .. the wiki has no examples and I'm a bit confused about the first parameter .. which is the target expressed as a rotation ... in llLookAt it is expressed as a vector and I can get that, but can anyone throw some light on what rotation needs to go in there - is it simply a region plane rotation of the object? I'm assuming not since it refers to the target ... which is where i'm getting confused ... would appreciate any help - example usage etc.

Thanks

sorry, just realised how dumb i was being, it's a target rotation - i just woke up
