As shown in Figure 5.41 , many parts in Linux 2.6 are not specific for TCP/IP, such as read/write functions and socket structure. From the viewpoint of a C programmer, analyze how Linux 2.6 organizes its functions and data structures to be easily initialized into different protocols. Briefly indicate the basic C programming mechanisms to achieve the goals
