|
* This file contains the non-rpc top-level rkinit library routines.
|
|
* The routines in the rkinit library that should be called from clients
|
|
* are exactly those defined in this file.
|
|
*
|
|
* The naming convetions used within the rkinit library are as follows:
|
|
* Functions intended for general client use start with rkinit_
|
|
* Functions intended for use only inside the library or server start with
|
|
* rki_
|
|
* Functions that do network communcation start with rki_rpc_
|
|
* Static functions can be named in any fashion.
