12.1 Text Protocol Server - launching and server loop

The code launching SurpriseServer and its main loop code is located in files src/server/surpriseserver.c and src/server/server.c . First, the command-line arguments are processed and passed appropriate parameters to the function launch_server() located in src/server/server.c. This function starts listening on a port if demanded and starts the server main loop. It waits for input and serves the client's demands (description of underlying language can be found in section Description of Text Protocol API). The client's demands are served as follows:

• Getresources demand is served by calling function get_resources() and printing the structure struct resources returned by this function.
• Getrootdirs demand is served by reading the request, calling function get_rootdirs() and printing the requested information about partition returned by this function.
• Commit demand is served by reading structure struct final, calling function commit in check-only mode and printing out the structure and the messages returned by the function.
• Confirm demand is served by reading structure struct final, calling function commit in modification mode and printing out the structure and the messages returned by the function.
• Close demand is served by shutting down the server.

If an error occurs the function prints out error message(s) and starts waiting for the client's next demand.
