Consider how to implement a mutex lock using the atomic compare_and_swap() hardware instruction (assuming atomic acquire() and release() hardware instructions do NOT exist). The following structure defines the mutex lock, where the value (available == 0) indicates that the mutex lock is available, and a value of 1 (available == 1) indicates that the mutex lock is unavailable. typedef struct {
int available;
}
mutex_lock;

Write C statement(s) to declare and initialize a shared variable named me_lock using the above structure type

Consider the following statements, then select one of the answers below: the signal() function shown below registers "sig_handler()" as the signal handler function for the sigkill signal, without the complexity of using when the sigkill signal is sent to a process running this code, by a user typing "kill -kill ", where the correct process id is used for to target the process, sig_handler() will be executed.

Install and use wireshark program ( send back screen shots and other vital information) case project 3-2: decode a tcp segment in a wireshark capture in this chapter, you walked through tcp segment to interpret the data included in its header. in this project, you use wireshark to capture your own http messafes, examine the tcp headers, and practice interpreting the data you'll find there. 1. open wireshark and snap the window to one side of your screen. open a browser and snap that window to the other side of your screen so you can see both windows.
