# libfb

Small library for interfacing with the Linux framebuffer. 

Compile and install:
```sh
make
sudo make install
```

Usage example:

```c
#define FB_IMPLEMENTATION // If linking dynamically with the library, omit this line
#include <fb.h>

int main() {
    Framebuffer fb = newFramebuffer("/dev/fb0");
    writeColourToFramebuffer(&fb, (Pixel){100, 100}, (Colour){255, 0, 0, 0});
    destroyFramebuffer(&fb);
}
```

Notes:

* Don't try to write to the framebuffer while in an X.org or Wayland session
* Your user must be in the `input` group before using, run the command `sudo usermod -a -G video $USER` to get permissions. Otherwise, the library will abort.
* This is intended to be a small library to make it easier for anyone to draw things to the screen. Just pixel rendering.
