Интерфейсы POSIX.1-2017 поддерживаемые в R3v2 (описание не завершено)

Поддержка разделена на субгруппы, представленные в стандарте
[POSIX] E.1 Subprofiling Option Groups

Поддержка и функционал включаются/отключаются с использованием определений в заголовке <unistd.h>. Реализация функций синхронизации основана на использовании атомарных не блокирующих операций с счетчиком семафора, см. <semaphore.h>.
