Solaris STREAMS Framework Enhancements

The STREAMS framework enhancements in the Solaris 8 operating environment provide more deterministic response times for real-time processes by ensuring that STREAMS processing uses a priority that does not conflict with the user process priority.

The Solaris 8 operating environment also enforces conformance to the Solaris operating environment DDI specified interfaces for the following Solaris STREAMS support functions:

• WR(queue_t)

• RD(queue_t)

• OTHERQ(queue_t)

• SAMESTR(queue_t)

Conformance to the Solaris operating environment DDI specified interfaces has been implemented by redirecting the functions listed above to the ddi.h implementations of these same functions in all cases of usage.

This enforced conformance introduces a risk of system failure in DDI non-compliant drivers and modules that incorrectly use the functions listed above. For DDI non-compliant drivers and modules, a version update of the non-compliant driver/module is required but no code changes are necessary.

For more detailed specifications of the functions listed above, see the STREAMS Programming Guide.
