The purpose of this project is to code a small data exchange program using UNIX signals.
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. • 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.
If you want it to send the other message on the bottom line after sending the first message, add this code in client.c main :
while (av[2][i] == '\0')
{
convert_char('\n', pid);
break ;
}
