Minitalk is a 42 Madrid Common Core project in which you have to code a small server-client data exchange program unsing UNIX signals.

Minitalk implements a UNIX signals based server-client communication system. The client sends input text converted to binary to the server through the user UNIX signals: SIGUSR1 and SIGUSR2. The server receive the transmission and decodes the text converting it back from binary and displaying it.

• The server must be launched first and will show its PID (process identifier).
• The client must receive as arguments the server PID and the string text to be sended.
• The server will receive the string text from the client and displays it almost instantly.
• The server can receive string texts from multiple clients without restarting.
• For the transmission you can only use the custom user UNIX signals: SIGUSR1 and SIGUSR2.

• The executables must be named server and client.
• There must be a Makefile that will compile the project.
• The program must be coded in C and must comply with 42 Norm.
• The program must compile with the -Wall -Wextra -Werror compiler flags.
• The program must handle possible errors: segmentation fault, bus error, double free, etc...
• The program mustn't have memory leaks.
• The use of global parameters is limited to only two: one for the server and one for the client.

• C compiler: gcc, cc, etc...
• make utility.
• libft library in the project root folder.

• make: compile project.
• make clean: deletes compilation files except the executables.
• make fclean: deletes all compilation files.
• make re: executes make fclean and make.

1. Clone the repository:

   git clone https://github.com/RaulSoftDev/minitalk.git cd minitalk/

2. Build the project:

   make

3. Execute the server:

   ./server

4. Execute the client in another terminal:

   ./client <PID> <String>
