Bug 32126

Summary: getopt(3) not Unix-98 conformant
Product: Base System Reporter: Wilhelm B. Kloke <wb>

Description Wilhelm B. Kloke 2001-11-20 09:20:01 UTC 
	I have been hit by a non-conformance to Unix standard (whatever this
	may mean). FreeBSD uses a global optreset to re-initialize
	some internal data structure for getopt. This is not conformant to
	Unix 98 spec (see opengroup.org man page) nor to Linux usage.

Fix: 

I propose to silently dropping use of optreset, as the reset
	condition can normally be signaled via optind. No applications
	should be affected, anyway. Grep -F -R optreset shows that
	contrib/nvi crypto/heimdal/lib/roken crypto/kerberosIV/lib
	are coming with their own getopt.c. Other apps using optreset
	are bin/chio bin/sh sbin/camcontrol sbin/ipfw sbin/mount
	sys/boot/ usr.sbin/ancontrol usr.sbin/inetd usr.sbin/mlxcontrol
	usr.sbin/mptable usr.sbin/raycontrol usr.sbin/wicontrol
	
	Camcontrol may have a problem. There is a discussion in  the comments.
	Just let camcontrol have its own getopt.c.

-standards hopefully know if optreset violates the 
standards we are trying to comform to and what to do 
about this.

The visibility of optreset was fixed in unistd.h's revision 1.50.

Oops, I actually meant 1.51.

The variable optreset is a extension to POSIX, it does not violate it.
