Routine Description:
|
|
|
|
Retrieves statistics from a designated service running at a down-level
|
|
server. Currently, the only services recognised are:
|
|
SERVER
|
|
WORKSTATION
|
|
|
|
Arguments:
|
|
|
|
ServerName - Where to run the API
|
|
ServiceName - Pointer to string designating service to get stats for
|
|
Level - At which to get info. Allowable levels are: 0
|
|
Options - Flags. Currently defined bits are:
|
|
0 Clear Statistics
|
|
1-31 Reserved. MBZ
|
|
Buffer - Pointer to pointer to returned buffer containing stats
|
|
|
|
Return Value:
|
|
|
|
NET_API_STATUS
|
|
Success - NERR_Success
|
|
Failure - ERROR_NOT_SUPPORTED
|
|
ServiceName was not "WORKSTATION" or "SERVER"
