| # Command Line Helper |
| |
| This documentation is incomplete. I would love your help to finish it up. Until that time, please read the documentation in [the `fio_cli.h` header file](https://github.com/boazsegev/facil.io/blob/master/lib/facil/services/fio_cli.h). |

| ## Overview |
| |
| The `sock` linrary was born to solve [many concerns](sock_why) that pop up when using the system sockets API directly. |
| |
| It supports TCP/IP sockets as well as unix doamin sockets. Pipes can also be attached to the library. |
| |
| The `sock.h` API can be divided into a few different categories: |
| |
| - General helper functions |
| |
| - Accepting connections and opening new sockets. |
| |
| - Sending and receiving data. |
| |
| - Read/Write Hooks. |
