A bit better than smoke

This is a simple client-server project demonstrating inter-process communication using signals in C. The server and client communicate by sending signals to each other to encode and decode messages.

• Signal Handling Function (handlemessage):
  • Accumulates bits received from the client.
  • Decodes bits into characters and prints the characters when a complete character is received.
  • Sends acknowledgment signals back to the client.

• Command-Line Argument Verification (args_verifier):

  • Verifies the correctness of command-line arguments.
  • Checks for a valid PID and the presence of a message. Abcense of a valid pid means there is an ongoing job.

• Sending Message Bits to Server (send_message):

  • Sends bits of the message to the server using signals.
  • Moves to the next character when all bits are sent.

• Acknowledgment Signal Handling (acknowledge):

  • Handles acknowledgment signals from the server.
  • Exits the client when a complete message is acknowledged.

1. Run the server:

   make
   ./server

2. In another terminal run the client with server PID which will be printed in the server's terminal:

   ./client [server_PID] "Hello, Server!"
