Bug 29492

Summary:	sysconf(_SC_NPROCESSORS_ONLN) not implemented, but defined by POSIX
Product:	Base System	Reporter:	June-Yen Huang <jihuang>

Description June-Yen Huang 2001-08-07 05:10:00 UTC

	Until now, the way to get number of CPUs under FreeBSD is use sysctl(3)
	only!  However, POSIX had defined sysconf(3) with _SC_NPROCESSORS_ONLN
	to do this, while FreeBSD series don't implement...
	
	Software Development will use standard/portable system call to get
	this information. I find this problem when I tracing BIND v9 codes.
	BIND9 developers accept a patch of using sysctl(3) instead sysconf(3).
	And they also request FreeBSD could follow POSIX in the furture.
