Size of Directory - High Level Programming

tantric · #1 06-28-2007

I have a C program to find out the total size of all the files in a directory.

So what it does is.. it scans through all the files in the directory and does a stat() on each of them and sums up the size returned by st_size .

Is there a quicker way to do this.. without doing a stat() on each one of them ? Basically I want to find the total size occupied by all files in a directory

thanks,
the tantric !

There is no quicker way to do it. And doing it right might be a bit harder than that. Consider:

Code:

$ echo stuff > file1
$ ln file1 file2
$ ls -is1 file1 file2
79074 1 file1
79074 1 file2
$

Is it ok to count both file1 and file2? They point to the same inode, so there is only one copy of the data.
