What is the D way to create a directory?

I can use the C function system("mkdir ...") but it doesn't seem 
very good to me.

Also, is there a way to require the root password of the user 
when going create the directory in a restricted folder (like 
/usr) AFTER the application has started?

Thank you.

It's not in the most obvious of places: 
http://dlang.org/phobos/std_file.html#mkdir

(But then again, an std.directory module would probably be a bit 
overkill...)

No idea, sorry.

 Thank you.

You could execute a system command and change your apps privileges but this
is a bad/risky way to do it.  I would use sudo or gksudo and launch the
command externally so that you don't grant your app root permissions and
then do something stupid.  If those actions are common I would only allow
root to use your app.

In Linux, files and directories have the "setuid" and "setgid" special flags
that allow ordinary users to execute binaries with temporary privileges of
binary file owner or group.

i.e., /usr/bin/passwd (owns root, with setuid) modifies /etc/passwd by any user
without write permission. /bin/ping (owns root, with setuid) allows any user to
send and listen control packages throw net interfaces.
