dbus getting Originator ID in C

[Tom Cocagne]

_get_sender() returns the unique DBus connection ID associated with
the caller. The DBus daemon provides the
"org.freedesktop.DBus.GetConnectionUnixUser" function to determine
which user id is associated with a unique connection id. From there,
you can obtain the human-readable username via the glibc's  getpwuid()
function.

I'm not very familiar with the DBus interface you're using but the
basic steps are:

1. conid = _get_sender()
2. userid = dbus_daemon.GetConnectionUnixUser(conid)
3. pwent = getpwuid(userid)
4. return pwent->pw_name
