SnmpDuplicatePdu function (winsnmp.h)
[SNMP is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. Instead, use Windows Remote Management, which is the Microsoft implementation of WS-Man.]
The WinSNMP SnmpDuplicatePdu function duplicates the SNMP protocol data unit (PDU) that the PDU parameter identifies, allocating any necessary memory for the duplicate PDU.
Syntax
HSNMP_PDU SNMPAPI_CALL SnmpDuplicatePdu(
[in] HSNMP_SESSION session,
[in] HSNMP_PDU PDU
);
Parameters
[in] session
Handle to the WinSNMP session.
[in] PDU
Handle to the PDU to duplicate. The SnmpDuplicatePdu function provides a unique handle to each PDU within the calling application.
Return value
If the function succeeds, the return value is a handle that identifies the new duplicate PDU.
If the function fails, the return value is SNMPAPI_FAILURE. To get extended error information, call SnmpGetLastError. The SnmpGetLastError function can return one of the following errors.
| Return code | Description |
|---|---|
|
The SnmpStartup function did not complete successfully. |
|
An error occurred during memory allocation. |
|
The session handle is invalid. |
|
The PDU handle is invalid. |
|
An unknown or undefined error occurred. |
Remarks
To release resources allocated by the SnmpDuplicatePdu function for a new PDU, a WinSNMP application must call the SnmpFreePdu function.
