It explains the design philosophy and usage of the application programming interface (API) to IRIS ATM. The document assumes familiarity with the IRIX networking environment (which is based on UNIX) and basic programming in the C language.

The IRIS ATM product is hardware and software that together allow applications to transmit and receive data over an ATM connection. IRIS ATM is an excellent data communication or networking solution for applications that require high-speed, constant, or nearly constant data rates.
