Vim Buffer has been modified [duplicate]

Question

I am trying to implement an AutoCmd in Vim that needs to be executed when the current buffer has been modified.

I have read through all the events available for AutoCmd in the docs but could not find something that would help determine when a buffer was modified or not.

This doesn't necessarily mean "when a buffer was written" because the action I need to trigger needs to be called when the buffer has been modified including being written.

Any ideas on how to implement a BufIsModified that could achieve this objective?

Note: not a duplicate of What is a vimrc function to determine if a buffer has been modified?, since this question is about an autocmd and not only the buffer modified check

Answer 1

The only thing popped into my mind is to use the CursorMoved and CursorMovedI events.
