* The original switch low level interface to switch was defined in
* /usr/include/nsswitch.h. Although it was marked "Project Private",
* it was none-the-less "exposed" and used by several apps. This
* file, nsswitch_priv.h will *not* go in /usr/include to limit "exposure"
* and contains new versions of the switch low level interface.
*
* This is a Project Private interface. It may change in future releases.
