Introduction to CPI-C

This section introduces the fundamental concepts of the Common Programming Interface for Communications (CPI-C). The following topics are covered:

• Windows CPI-C overview
• Windows CPI-C asynchronous support
• Using asynchronous call completion
• CPI-C call summary
• Conversation characteristics
• Side information
• Configuration
• Operating system considerations

CPI-C is a Systems Application Architecture adherent application programming interface (API) that allows peer-to-peer communications among programs in a Systems Network Architecture (SNA) environment.

Through CPI-C, programs distributed across a network can work together, communicating with each other and exchanging data, to accomplish a single processing task such as querying a remote database, copying a remote file, or sending and receiving electronic mail.
