# Minitalk
Minitalk is a simple project that requires you to use unix signals to send over strings between 2 programs.\
We can only use **SIGUSR1** and **SIGUSR2** and we can use the kill function to send them over

---
## Improvements
### Add support for multiple clients at the same time
##### Client
- client pings server every 100 msecs, and only starts writing after receiving SIGUSR2 back
- client sends \0 when done
#### Server
- server waits for a signal when pid = 1
- when server receives signal it sets the pid to the sender pid
- it keeps ignoring signals from other PIDs untill it received \0 from the current pid
- after \0 is received pid is set back to 1

## Bugs
*none*\
~~pid would return 0 when run in background~~

---
## Usage
1. Simply clone or download the repository
2. Run `make` in the cloned directory
3. Start the server with `./server` in the cloned directory
4. Open a second terminal in the same directory and run `./client [PID from server] ["Message in quotes"]`

---
## Tester
- add valgrind to tester
- check for -Wall -Werror -Wextra

#### Usage
1. Download test.sh into your own minitalk directory
2. Make the file executable `chmod +x test.sh`
3. Run `./test.sh` to start the test
