Re: [Mingw-users] chown command not found!

[Tor L. <tm...@ik...>]

And let me add that if one would want to implement (not "port") a
chown command for Windows (i.e. "native" Windows, not Cygwin or MSYS),
it is not possible to write a POSIX-style funtion with uid_t and gid_t
owner and group parameters to actually do it, as Windows doesn't have
integer uids and gids.

Instead one would need to look up the SIDs corresponding to the user
(and perhaps group) names mentioned on the command line, get the
security descriptor of the file, change the owner (and perhaps primary
group) SIDs in that, and set the file's security descriptor. Something
like that. Check MSDN for details, start browsing from SetFileSecurity
or SetNamedSecurityInfo for instance.
