tfInterfaceGetFromAddrPhysPort

ttUserInterface tfInterfaceGetFromAddrPhysPort	(
	ttConstSockAddrStoragePtr sockAddrStoragePtr,
	int physPort
	);

Function Description

This function returns an interface handle for the given socket/port combination.

Parameters

• sockAddrStoragePtr

  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.

• phyPort

  The physical port for which the interface handle is to be acquired.

Returns

• ttUserInterface

  This is the interface handle as returned by tfAddInterface().

• NULL

  Failure: The interfaceHandle does not exist for the given parameters.

Usage

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.
