NAME¶
fmt_human - write a human readable ASCII representation of a long integer
SYNTAX¶
#include <fmt.h>
size_t
fmt_human(char *
dest,unsigned long long
source);
DESCRIPTION¶
fmt_human writes a human readable ASCII representation of
source to
dest and returns the number of bytes written. The result resembles the
file size output of "ls -H"; 1000 becomes "1.0k", 1000000
becomes "1.0M" and so on for "G" and "T".
fmt_human does not append \0.
If
dest equals FMT_LEN (i.e. is zero), fmt_human returns the number of
bytes it would have written.
The output of fmt_human can not exceed 11 (assuming unsigned long long has 64
bits).
