I don't see windows implementations so this is not enough to block windows from
reaching here.

[dmichael (off chromium), 2013/09/09 20:37:15]

Why USE_ASH? Should this be OS_CHROMEOS? (And I guess this implies that this API
is ChromeOS-only? I would have guessed it could be supported on Windows at least
and probably also Mac.)

[kcwu, 2013/09/10 12:50:21]

Do you mean ASH is available on Windows? I think ASH is chromeos only.

[kcwu, 2013/09/10 12:50:21]

Yes, this API is ChromeOS-only. This API is designed in current simple form
because it is running in secure environment, i.e. ChromeOS. To support other
open platforms, the API must be extended to complex API/protocol for
authentication, verification, etc. which is not covered in this CL.

Done.
