1. The while seems ok. Remember, you are looping until select times out,
which means that there was no new data in the past 100ms. At that point you
send all the sound modifications that you've got, and then start again
looking at your input.
2. As for max_sock, the code was written
to provide you with the basic idea, but not with all the details.
The assignment specifications have since been updated to clarify the
calculation of this value.
