But that's:
a) not how normal Posix errno values are supposed to work. I
b) limited to using xattr, whichle getxattr is also exposed by glibc directly.
This really needs an explanation in the NOTES section, I'll see if I can come up with someting useful.

--- Comment #3 from Michael Kerrisk <[email protected]> 2013-01-18 23:00:47 --- Andrew, (and Christoph),
Others have also noted this point. For each of the relevant pages, I've simply added the text: "(ENOATTR is defined to be a synonym for ENODATA in <attr/xattr.h>.)"
