XSI_ADVANCED_REALTIME

The XSI_ADVANCED_REALTIME option group indicates that the _POSIX_CLOCK_SELECTION, _POSIX_CPUTIME, _POSIX_MONOTONIC_CLOCK, _POSIX_SPAWN, and _POSIX_SPORADIC_SERVER † options are enabled.

Enable this option group with CONFIG_XSI_ADVANCED_REALTIME.

An implementation that claims conformance to this option group shall also support the POSIX_TIMERS option group.
