Snowcast

Description

A music streaming server consisting of three programs: the server, the client controller, & the client listener.

Ensure you have gcc installed, as that is what the Makefile uses.
Run make in your terminal to make the 3 executables ./snowcast_server, ./snowcast_control, & ./snowcast_listener!

Running the 3 executables without arguments will tell you the necessary arguments to get going.

I did not implement origonal design doc, due to random malloc errors with the autograder. I rewrote the server, with the the design...

A "select_thread" controls accepting new clients and responding to commands from clients. It redirects the logic to separate helper functions to send replies.
The station information is held by an array. Each station has a thread that broadcasts to the listeners every half-second (at half the rate per second). At the bottom of this half-second, the station file is read into a buffer and threads are created off of this buffer, waiting to be released. At the top of this half-second, the station thread then bradcasts a cond variable to start all threads that send the station.
The users pointer containing the user data (along with the separate stations pointer) has a mutex users_mutex that allows safe-thread write and deletion. This pointer is also dynamic, using realloc when more memory is needed. There are a few memory optimizations implemented (see init_user(...)).
The code is well documented, so many smaller design choices can be read there :)
