My version of minitalk School 42 project @ Hive Helsinki

A small data exchange (client-server) program using UNIX signals.

Task description

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.

Bonus part

• The server acknowledges every message received by sending back a signal to the client.
• Unicode characters support!

How to run

• cd into the directory.
• make to compile.
• ./server to run server. Server will display its' process id, copy it!
• Client takes two arguments: server process id and a string to send. Run it in a second terminal like so: ./client_bonus {process_id} {your_message}. Example with process id 13629: ./client 13629 "Message to send 🦕"

How to run bonus

• cd into the directory
• make bonus to compile
• ./server_bonus to run server.
• ./client_bonus {process_id} {your_message} to send your message to server.
• This time server will send a confirmation to the client after the message was received. Very wow!
