Hey all,
I am looking for a good way to measure the size of a large integer for
instance when I run my program on /tmp I get:
pdudzins at gits:~/cs631/midterm$ ./a.out -l /tmp
drwxrwxrwx 2 root root 4096 .X11-unix
-rw------- 1 jschauma professor 10724 1
drwxr-xr-x 3 swatts student 4096 VisualGDB
*-rw------- 1 jschauma professor 2097152000 big*
-rwxr-xr-x 1 swatts student 56 dump-gdb-settings
-rw-r--r-- 1 jschauma professor 2041 f
-rw------- 1 jschauma professor 2041 file
drwxr-xr-x 2 jsexton student 4096 hsperfdata_jsexton
drwxr-xr-x 2 lxiong student 4096 hsperfdata_lxiong
drwxr-xr-x 2 snatara1 student 4096 hsperfdata_snatara1
-rw------- 1 fcannava professor 611 krb5cc_11084_S26665
-rw------- 1 jrisi student 605 krb5cc_11492_u17070
-rw------- 1 pdudzins student 611 krb5cc_11909_Iq7884
drwx------ 2 jschauma professor 4096 ssh-OkXFz27774
And the bolded line is messing up my column print lengh. When I measure the
size of the size I am doing it like this:
nlen_size = sizeof(a->fts_statp->st_size);
if (nlen_size > len_size)
len_size = nlen_size;
And I keep getting 8 instead of 10 which I am pretty sure the 8 bytes it
takes to store an int...
Has anyone tried casting this as a character array and taking the size that
way? Is there a library function that will just do this?
