nit: I think "Code" suffix is not necessary.

To all of Alok's comments here: I'd actually lean toward leaving this file
as-is. This is a direct upstream from internal.

[slan, 2015/06/16 14:57:48]

To keep this CL as clean as possible, this will be kept as a direct upstream.

+  NO_ERROR = 0,

[alokp, 2015/06/15 17:51:48]

nit: ERROR_NONE

[slan, 2015/06/16 14:57:49]

Keeping it for now.

The comment about volume is not clear to me.

[slan, 2015/06/16 14:57:48]

I agree, this seems to be the wrong place for this comment.
