Module Name:
admin.c
Abstract:
This module implements the top level admin request routines. All
routines within this module execute in the context of the server
service (or equivalent calling user mode process).
A routine that can complete an entire admin request
in the caller's context will return an appropriate AFP error to
the admin dispatch layer above.
A routine that must queue a worker to the FSP Admin queue will return
STATUS_PENDING to the admin dispatch layer above. This will indicate
to the dispatch layer that it should queue up the appropriate request.
In these cases, the routine's job is to merely validate any appropriate
input and return the STATUS_PENDING error code.
