The Solaris^TM 8 Operating Environment adds the remaining real-time system enhancements for Posix 1b.

• Arbitrary resolution, real-time timers
  Implements a new POSIX clock type: CLOCK_HIGHRES. For timers created with a clock_id of CLOCK_HIGHRES, the system attempts to use the optimal hardware source. The hardware source is transparent to the user and may change over the timer's lifespan.

• libthread priority inheritance
  Supports priority inheritance and ceiling protocols for synchronization by multithreaded real-time applications.

• Network priorities
  Priority scheduling and increased concurrency are provided through the Solaris STREAMS framework. This enables more responsive and predictable network events for real-time applications.

• Supports all platforms.
• No special hardware requirements. Some functions are different between CPU architectures, which may affect calling interface and timer granularity.

• Reduced development cost and complexity. developers assigning real-time attributes to networked applications can use the Solaris Operating Environment as an alternative to specialist real-time operating systems.

• Provides a a single-system solution. Applications using real-time features can co-exist with other non real-time applications.
