config POSIX_SYSCONF_IMPL_MACRO

	help
	  The sysconf() function is implemented compile-time constant via macros. This is the option
	  with the least overhead. The downside is that sysconf() is not an addressable function.

config POSIX_SYSCONF_IMPL_FULL
	bool "Full"
	help
	  The sysconf() function is implemented as a large integer-integer array. The advantage if this
	  option is that all sysconf() options can be queried and that the sysconf() symbol is
	  addressable.
