Routine Description:
|
||
|
||
This routine processes the server half of NetStatisticsGet in
|
||
the server FSD.
|
||
|
||
Arguments:
|
||
|
||
Srp - a pointer to the server request packet that contains all
|
||
the information necessary to satisfy the request. This includes:
|
||
|
||
INPUT:
|
||
|
||
Flags - MBZ
|
||
|
||
OUTPUT:
|
||
|
||
Not used.
|
||
|
||
Buffer - a pointer to a STAT_SERVER_0 structure for the new share.
|
||
|
||
BufferLength - total length of this buffer.
|
||
|
||
Return Value:
|
||
|
||
NTSTATUS - result of operation to return to the server service.
