#  TP_AIPS

- Groupe : 3IR C 2023-2024

## Building

Compile version `X` :

```
gcc -Wall -Wpedantic tsock_vX.c -o t_sockvX
```

Or compile all versions:

```
gcc -Wall -Wpedantic tsock_v1.c -o t_sockv1
gcc -Wall -Wpedantic tsock_v2.c -o t_sockv2
gcc -Wall -Wpedantic tsock_v3.c -o t_sockv3
gcc -Wall -Wpedantic tsock_v4.c -o t_sockv4
```

Generate zip archive (replace `TP1` with relevant indication) :

```
zip LACAU-ALNET-TP1.zip tsock_v*.c README.md
```


## Running

```
usage: ./t_sockv1 <-u> [-ps] [host] <port>
parameters: host  With -s, address of the host to connect to. Required with -s.
            port  Port to connect or bind to. Required.
options: -p       Runs a TCP/UDP sink. Incompatible with -s.
         -s       Runs a TCP/UDP faucet. Incompatible with -p.
         -u       Use UDP instead of TCP. Required.

usage: ./t_sockv2 [-psu] [host] <port>
parameters: host  With -s, address of the host to connect to. Required with -s.
            port  Port to connect or bind to. Required.
options: -p       Runs a TCP/UDP sink. Incompatible with -s.
         -s       Runs a TCP/UDP faucet. Incompatible with -p.
         -u       Use UDP instead of TCP.

usage: ./t_sockv3 [-psu] [-n nb_messages] [-l mess_length] [host] <port>
parameters: host         With -s, address of the host to connect to. Required with -s.
            port         Port to connect or bind to. Required.
options: -l mess_length  Size of the messages to send. Min 5. Max 1400. Default 30.
         -n nb_messages  Number of messages to send. Min 1. Default 10. Ignored with -p.
         -p              Runs a TCP/UDP sink. Incompatible with -s.
         -s              Runs a TCP/UDP faucet. Incompatible with -p.
         -u              Use UDP instead of TCP.
```

Example usage of v3 :

```
./t_sockv3 -p -l 15 4000            # receiver
./t_sockv3 -s -l 15 localhost 4000  # sender
```

Example usage of v4 :

```
./t_sockv3 -C -e -n 20 -l 15 localhost 4000   # client sender
./t_sockv3 -S -r -n 20 -l 15 4000             # server receiver
```

## Roadmap

- [X] tsock-v1
- [X] tsock-v2
- [X] tsock-v3
- [X] tsock-v4
  - [X] server can handle multiple requests simultaneously
  - [X] server doesn't stop after the connection ends
  - [X] both client and server can assume sender/receiver roles
