3.2.4.11 NetrWorkstationStatisticsGet (Opnum 13)

  • Artículo

The NetrWorkstationStatisticsGet method returns various statistics about the SMB network redirector on a remote computer.

 unsigned long NetrWorkstationStatisticsGet(
   [in, string, unique] WKSSVC_IDENTIFY_HANDLE ServerName,
   [in, string, unique] wchar_t* ServiceName,
   [in] unsigned long Level,
   [in] unsigned long Options,
   [out] LPSTAT_WORKSTATION_0* Buffer
 );

ServerName: A WKSSVC_IDENTIFY_HANDLE structure (section 2.2.2.1) that identifies the server (2). The client MUST map this structure to an RPC binding handle ([C706] sections 4.3.5 and 5.1.5.2). The server MUST ignore this parameter.

ServiceName: A pointer to a string specifying the name of the workstation service. This value MUST be ignored on receipt.

Level: The information level of the data. This value MUST be zero.

Options: This value MUST be zero.

Buffer: A pointer to a STAT_WORKSTATION_0 structure (section 2.2.5.11) that contains the statistical information.

Return Values: When the message processing result matches the description in column two of the following table, this method MUST return one of the following values ([MS-ERREF] section 2.2).

Value/code

Meaning

NERR_Success

0x00000000

The operation completed successfully.

ERROR_ACCESS_DENIED

0x00000005

Access is denied.

ERROR_INVALID_LEVEL

0x0000007C

The information level is invalid.

ERROR_INVALID_PARAMETER

0x00000057

One of the function parameters is invalid.

If the Level parameter does not equal 0x00000000, the server MUST fail the call and return ERROR_INVALID_LEVEL.

If the Options parameter does not equal 0x00000000, the server MUST fail the call and return ERROR_INVALID_PARAMETER. The server SHOULD<54> enforce security measures to verify that the caller has the required permissions to execute this routine. If the server enforces security measures and the caller does not have the required credentials, the server MUST fail the call and return ERROR_ACCESS_DENIED.

The server MUST fill in all the members of the STAT_WORKSTATION_0 structure that the Buffer parameter points to with the corresponding statistics about the SMB network redirector.

Some members of the STAT_WORKSTATION_0 structure (section 2.2.5.11) are implementation-specific values<55> that indicate certain performance characteristics of an operating system and do not apply to all servers. If a member value does not apply to the server, it MUST be set to zero.
