Name your executable files client and server. • You have to turn in a Makefile which will compile your source files. It must not relink. • You can definitely use your libft. • You have to handle errors thoroughly. In no way your program should quit unexpectedly (segmentation fault, bus error, double free, and so forth). • Your program mustn’t have memory leaks. • You can have one global variable per program (one for the client and one for the server), but you will have to justify their use. • In order to complete the mandatory part, you are allowed to use the following functions: ◦ write ◦ ft_printf and any equivalent YOU coded ◦ signal ◦ sigemptyset ◦ sigaddset ◦ sigaction ◦ kill ◦ getpid ◦ malloc ◦ free ◦ pause ◦ sleep ◦ usleep ◦ exit
You must create a communication program in the form of a client and a server. • The server must be started first. After its launch, it has to print its PID. • The client takes two parameters: ◦ The server PID. ◦ The string to send. • The client must send the string passed as a parameter to the server. Once the string has been received, the server must print it. • The server has to display the string pretty quickly. Quickly means that if you think it takes too long, then it is probably too long. 1 second for displaying 100 characters is way too much! • Your server should be able to receive strings from several clients in a row without needing to restart. • The communication between your client and your server has to be done only using UNIX signals. • You can only use these two signals: SIGUSR1 and SIGUSR2.
