src/usr.sbin/kvm_mkdb, branch stable/3

$Id$ -> $FreeBSD$

1999-08-29T15:57:45+00:00

Handle ELF symbols better. This fixes "vmstat -i" for the case

1998-10-28T06:39:41+00:00

where "/var/db/kvm_kernel.db" exists.

Note, kvm_mkdb tries to be clever, and skips rebuilding the database
if it thinks it's already up to date.  To see the effects of this
fix, you may need to manually delete "/var/db/kvm_kernel.db" and
then run "kvm_mkdb".

Update to use the new elf headers.

1998-08-17T08:47:19+00:00

Always support an elf kernel when given one.

1998-06-12T16:25:18+00:00

Statisize usage(). Add return(0) for -wall.

1997-09-24T06:44:12+00:00

Initial support for dealing with an elf /kernel. This is a loose hybrid

1997-08-30T23:35:00+00:00

of OpenBSD's elf nlist code for this, and our a.out version.  The OpenBSD
version was mainly a seek/read system with a mmap of the string table,
this one simply mmap's the lot (like the a.out version).

Obtained from:  a fair chunk from OpenBSD

compare return value from getopt against -1 rather than EOF, per the final

1997-03-31T05:11:47+00:00

posix standard on the topic.

Merge from Lite2 (use special dbopen flags)

1997-03-11T13:01:42+00:00

Sweep through the tree fixing mmap() usage:

1997-01-16T21:58:40+00:00

  - Use MAP_FAILED instead of the constant -1 to indicate
    failure (required by POSIX).
  - Removed flag arguments of '0' (required by POSIX).
  - Fixed code which expected an error return of 0.
  - Fixed code which thought any address with the high bit set
    was an error.
  - Check for failure where no checks were present.

Discussed with:	bde

Use the .Bx macro where appropriate.
