// There is very little commonality in extended attribute errors
// across platforms.
//
// getxattr return value for "extended attribute does not exist" is
// ENOATTR on OS X, and ENODATA on Linux and apparently at least
// NetBSD. There may be a #define ENOATTR on Linux too, but the value
// is ENODATA in the actual syscalls. FreeBSD and OpenBSD have no
// ENODATA, only ENOATTR. ENOATTR is not in any of the standards,
// ENODATA exists but is only used for STREAMs.
//
// Each platform will define it a errNoXattr constant, and this file
// will enforce that it implements the right interfaces and hide the
// implementation.
