pub fn llistxattr_query<P: Arg>(path: P) -> Result<usize>Expand description
llistxattr(path, NULL, 0)—Query the length of the list of extended
filesystem attributes, without following symlinks in the last path
component.
This function uses llistxattr 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 llistxattr, however keep in mind
that other processes may modify attributes at any time.
