Add CTLTYPE_QUAD to the list of types for which we don't want an empty

2004-03-02T05:42:52+00:00

value.  All the other numeric types are doing it . . .

Whitespace cleanup.

Add a command-line option to format output for human readability.

Currently, the only effect it has is to print some (but not all) numbers
using thousands separators.

Fix a few style glitches in the previous commit and make the

2003-11-01T07:06:04+00:00

tunable error message more brief.

Fix a 64 bit warning. Have set_T_dev_t() take a pointer to a size_t rather

2003-10-26T04:45:08+00:00

than a pointer to an int, since that is what it really wants anyway.

Wrap a long line in the previous commit

Have sysctl print out a more useful error message when it detects that the

2003-10-21T16:49:30+00:00

user has attempted to write to a read only, tunable value.

Tighten up the string->integer conversion in sysctl(8):

2003-06-15T06:26:08+00:00

(1) Reject zero-length strings for CTLTYPE_INT, _UINT, _LONG,
    _ULONG.  Do not silently convert to 0.

(2) When converting CTLTYPE_INT, _UINT, _LONG, and _ULONG, check the
    end pointer generated by strtol() and strtoul() rather than
    discarding it.  Reject the string if either none of the string
    was useful for conversion to an integer, or if there was
    trailing garbage.

I.e., we will not allow you to set a numeric sysctl to a value unless
we can completely convert the string argument to a numeric value.
I tripped over this when I put the following in /etc/sysctl.conf:

   kern.maxfiles="4000"

Ouch.
