Write a program to determine your system's byte ordering.
16.2
Write a program to print out which stat structure members are supported for sockets on at least two different platforms, and describe how the results differ.
16.3
The program in Figure 16.15 provides service on only a single endpoint. Modify the program to support service on multiple endpoints (each with a different address) at the same time.
16.4
Write a client program and a server program to return the number of processes currently running on a specified host computer.
16.5
In the program in Figure 16.16, the server waits for the child to execute the uptime command and exit before accepting the next connect request. Redesign the server so that the time to service one request doesn't delay the processing of incoming connect requests.
16.6
Write two library routines: one to enable asynchronous I/O on a socket and one to disable asynchronous I/O on a socket. Use Figure 16.21 to make sure that the functions work on all platforms with as many socket types as possible.
