Использование в приложениях (Application usage)
The conceptual model for scheduling semantics in POSIX.1‐2008
defines a set of thread lists. This set of thread lists is always
present regardless of the scheduling options supported by the
system. On a system where the Process Scheduling option is not
supported, portable applications should not make any assumptions
regarding whether threads from other processes will be on the
same thread list.
Обоснование (Rationale)
None.
Будущие направления (Future directions)
None.
