Document supported operating systems
The GitHub repo summary says that this is for 'Linux and Windows', but the docs don't seem to mention any specific operating systems and a look through old issues seems to indicate at least some level of support on Mac.
It would be useful to state explicitly in the documentation what operating systems are supported.
I know this isn't documentation, but I have tried this library on MacOS, Windows and Linux without issue.
+1 on more comprehensive documentation though
This library doesn't work on Mac without issue since it uses O_EXCL when creating. See https://stackoverflow.com/a/73752984/2708650 for more details about why this shouldn't be done.
