Key Changes (Cont'd)
XTI dropped
- Is retained as a separate specification but not required for POSIX or UNIX conformance
STREAMS optional
- An optional feature group for those systems that wish to support the functionality
Notes:
These two in particular were problematic for Linux
For systems who support XTI, there is still a specification
That is now not required for UNIX compliance
STREAMS is optional and still widely used in
Certatin markets
