I recommend consulting IBM's "z/OS Communications Server: IP Sockets Application Programming Interface Guide and Reference," IBM Publication No. SC27-3660. Here's the latest revision I can find, as a PDF, but please check for a later revision if you're reading this post some time after I wrote it.
http://publibz.boulder.ibm.com/epubs/pdf/f1a2d410.pdf I recommend choosing interfaces that support both IPv6 and IPv4 and making sure that your code ends up supporting both. Chapter 13, in particular, is likely to be helpful. You may also wish to refer to "z/OS UNIX System Services Programming: Assembler Callable Services Reference," IBM Publication No. SC23-2281, and perhaps other z/OS UNIX System Services references. As a general recommendation, don't try to "reinvent the wheel." UDP-related programming is quite low level. Is that programming work worth doing when somebody else (e.g. IBM, Eclipse Paho, etc.) may have already done it for you?
