pub fn listxattr_query<P: Arg>(path: P) -> Result<usize>Expand description
listxattr(path, NULL, 0)—Query the length of the list of extended
filesystem attributes.
This function uses listxattr with no buffer to just return the size of
the list. This can be used to determine the size of a buffer to
allocate for a subsequent call to listxattr, however keep in mind
that other processes may modify attributes at any time.
