How to hook socket or connect about fishhook

[kastiglione]

People have had issues with socket and/or connect in the past. One problem is that fishhook can only hook external calls, which means function calls within the same library generally cannot be hooked. In this case, calls to socket and connect from within the same library (libSystem) cannot be hooked. With the simulator, the system libraries are broken out into many sub-libraries, including libsystem_networking. With many sub-libraries, this means function calls from one sub-library to another can be hooked on the simulator, but on device where there's just a single libSystem, those same calls are within the same library and cannot be hooked.

Is there any inspiration how to hook connect in libSystem? inline hook can not work on un jailbreaking system. may be there is another way?
