Common Programming Interface for Communications


Common Programming Interface for Communications is an application programming interface developed by IBM in 1987 to provide a platform-independent communications interface for the IBM Systems Application Architecture based network, and to standardise programming access to SNA LU 6.2.
CPI-C was part of IBM Systems Application Architecture, an attempt to standardise APIs across all IBM platforms.
It was adopted in 1992 by X/Open as an open systems standard, identified as standard C210, and documented in X/Open Developers Specification: CPI-C.
