Description Alan Judge 1994-11-30 06:10:01 UTC 
	The TIOCSTAT ioctl (which admittedly isn't documented) doesn't
	seem to work.  From a quick look at the kernel code, it looks like
	it should.

	The only program that I know of that is affected by the
	problem is bash, but I would guess that any shells with
	command line editing would also be hit.

How-To-Repeat: 
Run:

#include <sys/types.h>
#include <sys/ioctl.h>

main()
{
	ioctl(1, TIOCSTAT, (char *)0);
}

State Changed
From-To: open->closed

The bug was caused by the ioctl requiring the address of an int 
to be copied in. This wasn't necessary - I've changed the ioctl 
to be a no-arg type. All things built using the TIOCSTAT ioctl will 
have to be re-compiled and linked.
