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.
