05241802a7 top: another readability fix 2007-08-29 18:34:26 +00:00
Denis Vlasenko
fc1e9951c6 vsz and rss are unsigned longs (ulong ~= width of void* => 
suitable for expressing total RAM in system). We account
for "32 bit in 64 bit" systems by storing kbytes, not bytes
there. Should allow for up to ~2000 Gb RAM on 32 bits.

been doing for the last couple days.

And it conflicts!  I've removed httpd.c from this checkin due to somebody else
touching that file.  It builds for me.  I have to catch a bus.  (Now you know
why I'm looking forward to Mercurial.)

c9c1a41c58 A couple things that got tangled up in my tree, easier to check in both than 
untangle them:

Rewrite u_signal_names() into get_signum() and get_signame(), plus trim the
signal list to that required by posix (they can specify the numbers for
the rest if they really need them).  (This is preparatory cleanup for adding
a timeout applet like Roberto Foglietta wants.)

Export the itoa (added due to Denis Vlasenko, although it's not quite his
preferred implementation) from xfuncs.c so it's actually used, and remove
several other redundant implementations of itoa and utoa() in the tree.
