Minitalk is a simple communication program that includes a client and a server. The server prints messages received from the client. The communication is done using UNIX signals, specifically SIGUSR1 and SIGUSR2.

• The server prints its PID when launched.
• The client sends a string to the server using the server's PID.
• The server displays the received string quickly.
• The server can handle multiple clients in succession without restarting.
• Communication between client and server is achieved using only SIGUSR1 and SIGUSR2 signals.

1. Clone the repository:

   git clone https://github.com/yourusername/minitalk.git

2. Navigate to the project directory:

   cd minitalk

3. Compile the server and client programs:

   make

1. Start the server:

   ./server

   • The server will print its PID, which will be used by the client.

2. Start the client with the server's PID and the string to send:

   ./client <server_pid> "<message>"

Example:

./client 12345 "Hello, World!"

• SIGUSR1: Represents a binary 0.
• SIGUSR2: Represents a binary 1.
