christos 6a02b7be66 - avoid coredump by returning NULL when read fails and don't keep following 
the list.
- avoid zerodivide.
XXX: still does not work, but at least it does not core-dump.

jdolecek ecb9302c7f if kvm_nlist() fails, nlisterr() would be called before the screen 
curses context would be initialized; just use errx() instead in this case
this fixes coredump for cases like 'systat -N /netbsd.gz', reported by Walt
on port-i386

in nlisterr(), wait a while (5 seconds currently) before exiting, so that
it would be actually possible to actually see the error

mrg 3cf4c73d05 iostat(8) and systat(8) support for separate read/write disk statistics. 
"iostat -x" now shows these (ala linux/solaris), but this is only splitting
the read/write bytes/transactions, not adding any new metrics.  "systat
iostat" now has two new commands to switch between combined/separate mode
for both it's numbers & bar modes.

cgd d594ce939b comment or delete text after CPP directives. 2001-01-16 02:50:27 +00:00
cgd 2af1e46eab __CONCAT does token pasting, not string concatnation. if something like: 
__CONCAT("foo","bar");
actually works to concantate strings, it's because the preprocessor expands
it into "foo""bar" as separate strings, and then ANSI string concatenation
is performed on that.  It's more straightforward to just use ANSI string
concatenation directly, and newer GCCs complain (rightly) about misuse
of token pasting.
