Chapter 1. What is RxSock?

RxSock is a Rexx function package providing access to the TCP/IP socket APIs available to the C programming environment. Most of the functions described in this reference are similar to the corresponding C functions available in the TCP/IP socket library.

It is assumed that you are familiar with the basic socket APIs and can reference those specific to the system. For more information, refer to the book Internetworking with TCP/IP, Volume I: Principles, Protocols and Architecture by Douglas Comer (Prentice Hall PTR).

The RxSock package requires TCP/IP support to be active on your system.
