CPI-C - AN API FOR DISTRIBUTED APPLICATIONS

Distributed applications have fostered the standardization of applicat ion programming interfaces for the underlying communication services. Three popular communication models-remote procedure calls, messaging a nd queuing, and conversations-support distributed applications across different networking protocols and physical media. Access to the conve rsational services of Advanced Program-to-Program Communication and Op en Systems Interconnection-Distributed Transaction Processing is provi ded by the Common Programming Interface for Communications (CPI-C), a standard, easy-to-use interface for communication programming. This pa per introduces the basic concepts of CPI-C, describes the conversation services available to programs, and presents examples of CPI-C progra mming.
