Re: [Discuss-gnuradio] inband signaling usb host

[George Nychis]

First off, I never received the original e-mail that you are responding to... was it sent 
to the board?  I don't see it in the archives either.  If so, this is the second e-mail 
I've not received simply related to the in-band signaling that was sent to the board.  I 
don't keep up with the other threads to know my overall loss ratio :)

I don't know if this was added in after your discussion or before, because I see no 
response to your e-mail either... whether it exists and was lost from my perspective, I 
have no clue :)  But...
response_recv_raw_samples(invocation_handle, samples, timestamp, properties)

I think that is what this method is for, you specify the timestamp at which the first 
sample in the samples was received by the A/D converter.  So that would follow along with 
your suggestion.

In response to Eric's discussion question in the doc, I say we use different modes.  I 
think that being able to specify the number of cmd_recv_raw_samples commands and a flag 
would provide the most flexibility and functionality.
