glibc/sysdeps/mach/hurd/ioctls.h
Roland McGrath 9e3db9cd59 Thu Feb 15 13:57:08 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu>
* mach/Machrules: Use -include for $(*.ir).

	* hurd/hurd/ioctl.h (_HURD_HANDLE_IOCTLS): Mask off type bits in
	request values.
	* sysdeps/mach/hurd/ioctls.h (_IOC_NOTYPE): New macro.
	(_IOT_COUNT2): Field is 3 bits, not 2.
	* sysdeps/mach/hurd/ioctl.c: Ignore handler if it fails with ENOTTY.
	* hurd/hurdioctl.c (_hurd_lookup_ioctl_handler): Mask off type
	bits before looking up handler.
	(fioctl): Use __hurd_dfail.
	(fioctl, fioclex): Use ENOTTY for bogus request instead of EGRATUITOUS.

Wed Feb 14 00:21:17 1996 David Mosberger-Tang  <davidm@azstarnet.com>

	* sysdeps/alpha/memchr.c (memchr): loop searching for matching
	character bailed out one too early; changed constant 6 to
	7 to fix this.
