### 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`](https://man7.org/linux/man-pages/man3/free.3.html)

- [`free`](https://man7.org/linux/man-pages/man3/free.3.html)

- [`write`](https://man7.org/linux/man-pages/man2/write.2.html)

- [`getpid`](https://man7.org/linux/man-pages/man2/getpid.2.html)

- [`signal`](https://man7.org/linux/man-pages/man2/signal.2.html)

- [`sigemptyset & sigaddset`](https://man7.org/linux/man-pages/man3/sigsetops.3.html)

- [`sigaction`](https://man7.org/linux/man-pages/man2/sigaction.2.html)

- [`pause`](https://man7.org/linux/man-pages/man2/pause.2.html)

- [`kill`](https://man7.org/linux/man-pages/man2/kill.2.html)

- [`sleep`](https://man7.org/linux/man-pages/man3/sleep.3.html)

- [`usleep`](https://man7.org/linux/man-pages/man3/usleep.3.html)

- [`exit`](https://man7.org/linux/man-pages/man3/exit.3.html)

## Compilation

### 1 - First things first, you need to clone this repository:

```python

git clone https://github.com/RogerioLS/Mini_Talk-42sp

```

### 2 - Go to Minitalk and run make

```python

cd Mini_Talk-42sp/

make

```

### 3 - Run server to get its PID and use it on client side to send the message you want. 

```python

./server

./client  

```

and that's basically it! :)
