Network InterProcess Communication (NetIPC) is a set of programmatic
calls that can be used to exchange data between peer-to-peer processes
on the same or different nodes in an Hewlett-Packard NS network.
Any process can initiate communication, and any process can send
or receive messages by means of common intrinsics. NetIPC 3000/XL
is a version of NetIPC that can be used in programs written for
MPE XL based computer systems.
NetIPC provides programmatic access to the Transmission Control Protocol
(TCP), which is the Transport-Layer protocol used by NS 3000/XL
link products.
NetIPC 3000/XL is provided with the purchase of any
NS 3000/XL link product. With the purchase of the X.25
XL System Access link product, NetIPC access to TCP (level 4) and
X.25 (level 3) is provided.
Intended Audience of this Manual
In order for you to use NetIPC, you should be familiar with
MPE XL, the operating system on which NetIPC 3000/XL
can be used. You should also be familiar with the TCP protocol and
a high-level language such as Pascal.
If you are using direct access to level 3 (X.25), you should
be familiar with the X.25 protocol and the HP 3000 products that
provide X.25 network communication.
Organization of the Manual
Following is a summary of how this manual is organized:
Chapter 1 “NetIPC Fundamentals” explains
how to establish connections, send and receive data over connections,
and shutdown connections between processes using NetIPC TCP
access or X.25 level 3. This chapter also introduces some of the
NetIPC calls.
Chapter 2 “Cross-System NetIPC” describes what NetIPC
calls need to be considered for a cross-system application (using
TCP access) between an HP 3000 Series 900 and either an HP 1000, HP 9000,
or personal computer.
Chapter 3 “NetIPC Intrinsics” provides a detailed
description of each NetIPC intrinsic, in alphabetical order. This
chapter also explains programming considerations, syntax, and the
structure and function of several parameters that are common to
multiple NetIPC intrinsics.
Chapter 4 “NetIPC Examples” provides sample programs
using NetIPC intrinsics for peer-to-peer process communication for
both TCP access and X.25 level 3 access.
Appendix A “IPC Interpreter (IPCINT)” describes how to use
the IPCINT software utility which provides an interactive interface
to the NetIPC intrinsics used for programmatic access to X.25 level
3.
Appendix C “Error Messages” includes a list of SOCKERRs
and the corresponding protocol module errors returned in the
IPCCHECK intrinsic, and provides a table of NetIPC errors (SOCKERRs)
returned in the result parameter of the NetIPC intrinsics.
