You'll want to document each of the messages.

[Mike West, 2014/08/19 08:37:15]

Indeed!

nit: alignment (applies throughout)

[Mike West, 2014/08/19 08:37:15]

Done.

[Ilya Sherman, 2014/08/15 20:42:37]

nit: Please include a variable name for this one too.  (Applies throughout.)

[Mike West, 2014/08/19 08:37:15]

Done.

[Ilya Sherman, 2014/08/15 20:42:37]

nit: "Request" is a little too generic -- perhaps "RequestCredentials" or
something like that?

[Mike West, 2014/08/19 08:37:15]

Done.

:(

Or ':_(', I guess.

+IPC_MESSAGE_ROUTED2(CredentialManagerMsg_RequestResponse,

[Ilya Sherman, 2014/08/15 20:42:37]

nit: This sounds like it is requesting a response, rather than responding to a
request.  Perhaps there's a less generic name we could use that would be clearer
as well?  Something like "SendCredentials"?

[Mike West, 2014/08/19 08:37:15]

Done.
