You don't have to consume all the incoming samples.  Just consume the
number you want, and return the number of output samples that you
produced (I assume it's 100) as the result of work or general_work.

Sorry, I wasn't clear what your second question was.

On a separate topic, you may want to consider updating to the
subversion trunk, or at least the 3.0 release so that you are using
the latest code and naming conventions for the mod/demod and packet
handling code.  It's not crucial, but there may be stuff we've fixed
since you started working.  Also, I don't keep track of the old stuff
in my head, and since you are using something called gmsk2 (that
hasn't existed for a couple of months), I know that you're not up to
date ;)
