Dear Paul,
I'd recommend taking this to the USRP-users mailing list (in CC), since
it's not really GNU Radio-related.
Since that clock rate setting doesn't really "exist" until the device
is operating, you can't query that from any program than the program
currently using the USRP (but that program would know, anyway, because
it either set the master clock rate to 184.32 MHz or it left it at 200
MHz).
Best regards,
Marcus
