Certainly a plumber could answer your questions, but you should be able to figure this out yourself. It has to be at least a 3" diameter pipe for a conventional toilet drain. Assuming the pipe is large enough, it would almost certainly be intended for a toilet drain, so pour a 5 gallon bucket of water into it. Check the assumed vent line the same way. If you water into the vent, you should be able to hear it through the big pipe. As you apparently realize, a toilet flange is supposed to be bolted to the floor. Well, sometimes people don't always follow directions. If a flange was friction fit to the drain and rested flat but unbolted to the floor, it would still work and with a tight fit, it might not leak. If the floor was flat and the users didn't push and pull, the toilet might also not rock and roll. It's also possible that it was never connected, just roughed in. That is the next point to check anyway. A toilet rough-in is 12" center of drain to finished wall. 10" to 14" can be accomodated, but 12" is standard. That's about all you have to determine to know if this will work or not.
