Research

SDL is used for low-level accessing of your keyboard, mouse, and other hardware features(graphics). For ex. If you want to make your mouse or keyboard move a character, SDL has an api that will use your mouse or keyboard input in a function. SDL will also allow you to renders things.

SDL offers many different API categories and can be accessed with this link https://wiki.libsdl.org/APIByCategory. Thankfully, this saves you time and effort.

We seem to mostly need the input events and video apis.

How to use SDL

1. Install the source code and configurations to even use the SDL library https://wiki.libsdl.org/SourceCode
2. Build and run the code https://wiki.libsdl.org/Installation

Things to do

1. figure out which APIs you want to use and which are compatible with pre-existing code
2. See if other libraries can be used with SDL to render a better UI.

**** SDL can be used with the OpenGL API or Direct3D API for 3D graphics****
