needs void no?

A good way to ensure your code builds is to run it in Cerberus.
Steps to do so:

  1. Commit to ur branch in embedded base
  2. Clone Cerberus
  3. Enter the ./Drivers/Embedded-Base directory in Cerberus and run git fetch and git checkout <your-branch-name>
  4. Now update cerberus Makefile with the relevant .c file you want to test
  5. run ner build and observe any errors/warnings

Lmk if you have questions about these steps, if you need instructions to setup ner build check here
