The Single UNIX Specification
A single set of APIs supported by every UNIX system.
Shifted the focus from incompatible UNIX system product implementations to compliance to a single set of APIs.
If an OS meets the specification and commonly available applications run on it, then it is open.
Notes:
In the next few slides we will look at the
Single UNIX Spec version 2 and then the Version3
Specification
(At the moment LSB is aligned with the Version 2 spec)
