# 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
|
