A return value of 0 should typically mean something went wrong
somewhere and didn't return the right value to us.

- For the print message, I think we should just print the value
  instead of UNKNOWN. Let the user / developer decide what to do with
  it.

- As for trying other mechanism to find the frequency now, maybe you
  are right and looking for an alternate way is the right way to go.
  And that would be consistent with existing behavior too.
