Addressing AF_IUCV sockets in applications
To use AF_IUCV sockets in applications, you must code a special AF_IUCV sockaddr structure.
Application programmers: This information is intended for programmers who want
to use connections that are based on AF_IUCV addressing in their applications.
The primary difference between AF_IUCV sockets and TCP/IP sockets is how communication partners are identified (for example, how they are named). To use the AF_IUCV support in an application, code a sockaddr structure with AF_IUCV as the socket address family and with AF_IUCV address information. For more information, see the af_iucv man page.
