Single UNIX Specification Conformance
SCO has made several enhancements and modifications to the SCO UnixWare 2.1 system to
conform to the Single UNIX specification put forth by the industry and widely adopted by all
leading UNIX system vendors.
This specification provides a rich set of interfaces that cover a broad range of historical UNIX
interfaces, a stable specification against which to write applications that will be portable to many
platforms, and a stable methodology to evolve the specification in a manner that is not under the
control of any single vendor or vendor consortium. It contains about 1170 separate APIs derived
from those used by the most popular business applications running on UNIX systems. This
approach, far superior to the earlier lowest common denominator, reliably delivers to the market
the benefits of a single, standard operating system: application and information portability,
flexibility and freedom of choice for customers . The update includes several enhancements to
the operating system components listed below:
• System Interface and Headers Definitions, Issue 4, Version 2 (XBD)
• Commands and Utilities, Issue 4, Version 2 (XCU)
• Networking Services, Issue 4 : Three sets of networking services are defined in the
Single UNIX Specification, X/Open Transport Interface (XTI), XPG4 Sockets, and IP
Address Resolution interfaces.
