when off. +600 bytes when on top: reorder columns, so that [P]PIDs are together and VSZ/%MEM are together. Makes more sense

these are resulting fixes
2006-11-05replace /proc scanning code by more versatile one.Denis Vlasenko
Use it where appropriate. Stop scanning /etc/passwd *for every process*!!! (uid->username) top: reduce memory usage - we won't save unneeded fields from /proc info anymore. Downside: ~+250 bytes of code
2006-11-05top: improve CPU% calculationDenis Vlasenko
style fixes
2006-11-01PID should be stored in pid_t, not int or long.Denis Vlasenko
find_pid_by_name() was returning 0 or -1 in last array element, but -1 was never checked. We can use just 0 intead.
2006-10-27top: batch mode should output all processesDenis Vlasenko
2006-10-14add open_read_close() and similar stuffDenis Vlasenko
2006-10-08attempt to regularize atoi mess.Denis Vlasenko
2006-10-06dnsd fix; option_mask32 added. dnsd needs more love.Denis Vlasenko
2006-10-03getopt_ulflags -> getopt32.Denis Vlasenko
It is impossible to formulate sane ABI based on size of ulong because it can be 32-bit or 64-bit. Basically it means that you cannot portably use more that 32 option chars in one call anyway... Make it explicit.
2006-09-29top: add support for -b, -n <iterations>Denis Vlasenko
2006-09-09top: fixed wrong comment, made error message more clearDenis Vlasenko
2006-08-03Remove bb_ prefixes from xfuncs.c (and a few other places), consolidateRob Landley
things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only had one user), clean up lots of #includes... General cleanup pass. What I've 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.)
2006-06-30Make another warning go away.Rob Landley
2006-06-28Top was catching sigterm (and fumbling sigint) so it could reset the terminalRob Landley
type on the way out, but the signal handler didn't exit. Plus it did unnecessary things with sigaction. This code is overgrown and needs a serious weed-whacking...
2006-06-02- move #include busybox.h to the very top so we pull in the configBernhard Reutner-Fischer
and eventual platform specific includes in early.
2006-05-27Consolidate #include <sys/time.h> so libbb.h does it.Rob Landley
2006-05-19- make it C89 compatible; Declarations in the middle of a function is of courseBernhard Reutner-Fischer
fine in C99, but it really serves no purpose other than breaking compilation on C89 compilers. Thanks to Rich Felker for pointing this out.
2006-05-04Fix allbareconfig.Rob Landley
2006-04-24From Denis Vlasenko:Rob Landley
* CPU% = process[i].ticks/sum(process[i].ticks) * busy_cpu_ticks/total_cpu_ticks * got rid of empty line under "Load average" line   and used last line - +2 visible processes * do not do float conversion of loadavg, just read it as string from /proc * fix display on small screens * dropped unused .stime, .utime fields * a few variables were renamed * style fixes
2006-04-12- patch from Denis Vlasenko to add and use bb_xchdir()Bernhard Reutner-Fischer
2006-02-15add last terminal line"Vladimir N. Oleynik"
2006-02-14restore change by Denis Vlasenko: file_to_buf must vary fast, best if inline"Vladimir N. Oleynik"
