From 91c9388715182a71173f2da71d74173221460412 Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Tue, 3 Apr 2001 23:14:29 +0000 Subject: Place a temporary bandaid on the ls/du/df human-readable issue. This method is not going to scale up as well as I would like, and Matt Kraai and I have discussed a better long term solution. But for now this will at least make all the human-readable apps give correct answers. Please test the human readable/non-human readable options on your systems!!! -Erik --- libbb/human_readable.c | 47 ++++++++++++++++++++++++++++------------------- 1 file changed, 28 insertions(+), 19 deletions(-) (limited to 'libbb/human_readable.c') diff --git a/libbb/human_readable.c b/libbb/human_readable.c index 36783fac7..ff2175175 100644 --- a/libbb/human_readable.c +++ b/libbb/human_readable.c @@ -28,26 +28,35 @@ #include #include "libbb.h" -static char buffer[10]; -static const char *suffixes[] = { "", "k", "M", "G", "T" }; -const char *make_human_readable_str(unsigned long val, unsigned long not_hr) -{ - int suffix, base; - if (not_hr) - sprintf(buffer, "%lu", val); - else - for (suffix = 0, base = 1; suffix < 5; suffix++, base <<= 10) { - if (val < (base << 10)) { - if (suffix && val < 10 * base) - sprintf(buffer, "%lu.%lu%s", val / base, - (val % base) * 10 / base, suffixes[suffix]); - else - sprintf(buffer, "%lu%s", val / base, suffixes[suffix]); - break; - } - } +const char *make_human_readable_str(unsigned long val, unsigned long hr) +{ + int i=0; + static char str[10] = "\0"; + static const char strings[] = { 'k', 'M', 'G', 'T', 0 }; + unsigned long divisor = 1; - return buffer; + if(val == 0) + return("0"); + if(hr) + snprintf(str, 9, "%ld", val/hr); + else { + while(val >= divisor && i <= 4) { + divisor=divisor<<10, i++; + } + divisor=divisor>>10, i--; + snprintf(str, 9, "%.1Lf%c", (long double)(val)/divisor, strings[i]); + } + return(str); } + + +/* END CODE */ +/* +Local Variables: +c-file-style: "linux" +c-basic-offset: 4 +tab-width: 4 +End: +*/ -- cgit v1.2.3
