> (a) What do they do?
The general design philosophy of the Unix library is to simply forward the call to the equivalent C function, turning errors in to a `Unix.Error` exception. So the question is usually resolved by looking at the documentation of the C function. In that particular case if the file doesn't exist you will get an exception with the NOENT error.

I think it would be good if the documentation of the Unix module linked to the documentation of the C functions in the POSIX standard (you will notice the ocamlunix book usually does this when functions are introduced).
> (c) Are these suitable functions to determine if a file exists?
Yes. Don't forget to retry the call on EINTR though.
Best,
Daniel
