DESCRIPTION

This Product Standard is for operating system environments providing realtime services based on IEEE Std 1003.13 Profile PSE54. This supports applications portability at the source code level and includes the provision of a standard operating system interface and environment, including a full file system implementation and support for multiple users.

CONFORMANCE REQUIREMENTS

A single configuration of the system shall support the requirements described in Section 9 of IEEE Std 1003.13 with the following exceptions:

• The system need not support the following POSIX.1 Option Requirements defined in Table 9-2, Section 9.2.1 of IEEE Std 1003.13-2003:
  • _POSIX_TRACE
  • _POSIX_TRACE_EVENT_FILTER
  • _POSIX_TRACE_INHERIT
  • _POSIX_TRACE_LOG
• The system need not support the large file capabilities of the Shell and Utility Requirements defined in Section 9.4 of IEEE Std 1003.13-2003.
• The system need not support POSIX 1003.26-2003.
• The system need not support POSIX.5c Interfaces (Ada Language Option)
