In a script, I want to retrieve my LookAt vector, but I can't find an LL function for that. Help?

In a script, I want to retrieve my LookAt vector, but I can't find an LL function that retireves it, only sets or rotates around it.  What should I be using to retrieve my LookAt?

You can't, because there is no such LSL function.  You can answer some of the questions that you might be trying to address in other ways, though.  For example, if you're in mouselook you can use llCastRay to figure out what is along the vector between you and wherever your camera is pointing.  This code snippet

            vector start = llGetCameraPos();            list results = llCastRay(start, start+<50.0,0.0,0.0>*llGetCameraRot(),[RC_REJECT_TYPES,RC_REJECT_PHYSICAL|RC_REJECT_AGENTS|RC_REJECT_LAND,RC_DETECT_PHANTOM,FALSE,RC_DATA_FLAGS,RC_GET_ROOT_KEY,RC_MAX_HITS,5]);

will direct a cast ray 50.0 m from you along your line of sight and will return the UUID and position of the first object that lies along that path.  That's considerably more reliable than the notoriously sloppy LookAt function in your viewer.
