Subject: st_size of a symlink
Date: Mon, 23 Jul 2012 17:55:43 +0200 [thread overview]
Message-ID: <500D73FF.1070504@nod.at> (raw)
Hi!
lstat(2) on /proc/$pid/exe gives me a stat object where st_size is 0.
Or:
rw@mantary:~> ls -l /proc/$$/exe
lrwxrwxrwx 1 rw users 0 23. Jul 17:02 /proc/16902/exe -> /bin/bash
The lstat(2) manpage says:
"The st_size field gives the size of the file (if it is a regular file
or a symbolic link) in bytes. The size of a symbolic link is the length
of the pathname it contains, without a terminating null byte."
This property is also used in the example in the readlink(2) manpage.
Is this a procfs issue or is the manpage wrong?
Thanks,
//richard
