# ftpd

FTP Server for 3DS/Switch/Linux.

## Features

- Appears to work well with a variety of clients.
- Supports multiple simultaneous clients. The 3DS itself only appears to support enough sockets to perform 4-5 simultaneous data transfers, so it will help if you limit your FTP client to this many parallel requests.
- Cutting-edge [graphics](#dear-imgui).

- Exit on NDS/3DS with START button
- Exit on Switch with PLUS button

- Toggle backlight on NDS/3DS with SELECT button
- Toggle backlight on Switch with MINUS button

- Emulation of a /dev/zero (/devZero) device for network performance testing
  - Example retrieve `curl ftp://192.168.1.115:5000/devZero -o /dev/zero`
  - Example send `curl -T /dev/zero ftp://192.168.1.115:5000/devZero`

## Dear ImGui

ftpd uses [Dear ImGui](https://github.com/ocornut/imgui) as its graphical backend.

Standard Dear ImGui controller inputs are supported.
