More Posix stuff on Windows

More Posix stuff on Windows

[Eli Zaretskii]

I'd like to add emulations of a couple of Posix functions to make a
few Guile procedures available on Windows.  Specifically, getaffinity,
setaffinity, getpriority, and setpriority can work on Windows, once
the emulations of the corresponding C APIs are written, which isn't
hard.

Is it OK to add those to win32-proc.c?  (Perhaps the file should be
renamed to posix-w32.c or some such now, since it is no longer only
about processes.)

If you agree, I will post the patches here.

The usual answer to this would be Gnulib.  Is this again a case where
that seems difficult, because the process-related code is a
prerequisite?

We must really try hard to push such things into Gnulib.

Thanks,

No, these are unrelated to the Gnulib process-related code.  They are
stand-alone functions.

I agree, in theory.  In practice, it's harder than I'd expect.  E.g.,
the patches I sent for nl_langinfo, an existing Gnulib module, were
left without a single comment for the last 4 weeks.  The only
conclusion I can draw from this and similar experiences is that the
Gnulib maintainers are not really interested in improving support for
Windows, even if someone else writes and tests the code.

On top of that, there are no Gnulib modules for the above-mentioned
functionality.  Creating a Gnulib module from scratch is a lot of
effort for me and a lot of overhead (write Autoconf macros,
documentation, testing on other platforms, to which I have no easy
access, etc.).

So I guess these will remain my local changes, sigh.
