fsp_dir.c

|
Abstract:
|
||
|
|
||
|
This module contains the entry points for the AFP directory APIs. The API
|
||
|
dispatcher calls these. These are all callable from FSD. All of the APIs
|
||
|
complete in the DPC context. The ones which are completed in the FSP are
|
||
|
directly queued to the workers in fsp_dir.c
