ReadDirectoryChangesW is present in pyfilesystem, that Nick mentioned
in another thread. In fairness you shouldn't expose this without
exposing inotify for Linux, and whatever nasty equivalents are
available on other systems.
pywin32 gives you full access to the Windows kernel interface. The
same functionality is not bundled in the standard library for Linux.
To use Massimo's example regarding file locking, just this morning I
had to write a ctypes wrapper around struct flock for this purpose
because the fcntl module is only a partial implementation. If the full
Windows API is made available, you might as well complete some of
those half-done modules now that the single biggest sore thumb
(Windows) for OS interfaces will be laid bare.
Python is well respected for its cross platform support. Making
bindings available in both cross platform and native forms will
greatly improve uptake of Python. My thoughts are that more effort
should be made to completely expose Unix/Linux/Mac interfaces before
(or simultaneously) with making the entire Windows API available.
