About

The purpose of this project is to code a small data exchange program using UNIX signals.

Mandatory

• Produce server & client executables
• client must communicate a string passed as a parameter to server (referenced by its process ID) which then displays it
• Use SIGUSR1 & SIGUSR2 signals ONLY

Bonus

• Add reception acknowledgement system
• Support Unicode characters

Allowed Functions

• malloc
• free
• write
• getpid
• signal
• sigemptyset & sigaddset
• sigaction
• pause
• kill
• sleep
• usleep
• exit

Behaviour:

1. By running the server executable we start up the server and it displays its process id:

2. By running the client with the process id from the server we can send strings to the server

3. Server receives bits containing the information, translates them to characters and prints the result as a string:

Additional behaviour:

1. The client can also send Unicode format characters and recieve acknowledges

2. The server interprets and displays them correctly
