I think you can use following code:<div class="im"><br>
len = 1;<br>
while (size / 10) {<br></div>
len++;<br>
}<br>
<br>
to get the len of the size.<div class="im"><br>

Hey all,<br>
I am looking for a good way to measure the size of a large integer for<br>
instance when I run my program on /tmp I get:<br>
<br>
pdudzins@gits:~/cs631/midterm$ ./a.out -l /tmp<br>
<br>
drwxrwxrwx 2 root root 4096 .X11-unix<br>

And the bolded line is messing up my column print lengh. When I<br>
measure the size of the size I am doing it like this:<br>
<br>
nlen_size = sizeof(a->fts_statp->st_size)<u></u>;<br>
if (nlen_size > len_size)<br>
len_size = nlen_size;<br>
<br>
And I keep getting 8 instead of 10 which I am pretty sure the 8 bytes<br>
it takes to store an int...<br>
<br>
Has anyone tried casting this as a character array and taking the size<br>
that way? Is there a library function that will just do this?<br>
