This is a very simple file system watcher for Odin, using windows api (IOCP)
This is a not a complete solution for File Watching, just a simple layer on top of ReadDirectoryChangesW + IOCP. So it will only accept directories to watch.
Making it capable of watching only files, or to better control when events occur(see the issue below), will be left to the user to develop, since there are tradeoffs that i don´t want this lib to made.
The function ReadDirectoryChangesW() will dispatch double MODIFIED events, and its by "design". (you can read more here )
This project will not solve this problem, since its intention is to be a very simple layer on top of the related functions of the windows api.
