This function returns an interface handle for the given socket/port combination.
- The pointer to a sockaddr_storage structure containing a configured IP address on the queried interface. A NULL pointer can be used to find the first configured interface on the given physPort.
- The physical port for which the interface handle is to be acquired.
- This is the interface handle as returned by tfAddInterface().
- Failure: The interfaceHandle does not exist for the given parameters.
There is a one-to-one correspondence between an IP address and the physical port/interface combination. This function returns the interface handle for the given physical port and IP address. For details on Strong End System Model see Appendix C: Strong End System Model / Weak End System Model.
