3.1.4.3.12 IWbemServices::PutInstance (Opnum 14)
The IWbemServices::PutInstance method creates or updates an instance of an existing class.
The PutInstance method opnum equals 14.
-
HRESULT PutInstance( [in] IWbemClassObject* pInst, [in] long lFlags, [in] IWbemContext* pCtx, [out, in, unique] IWbemCallResult** ppCallResult );
pInst: MUST be a pointer to an IWbemClassObject interface object that MUST contain the class instance that the client wants to create or update. This parameter MUST NOT be NULL.
lFlags: Flags that affect the behavior of the PutInstance method. Flag behavior MUST be interpreted as specified in the following table.
-
The server MUST accept a combination of zero or more flags from the following table and MUST comply with all the restrictions in a flag description. Any other DWORD value that does not match a flag condition MUST be treated as not valid.

Value
Meaning
WBEM_FLAG_USE_AMENDED_QUALIFIERS
0x00020000
If this bit is set, the server SHOULD ignore all the amended qualifiers while this method creates or updates a CIM instance.
If this bit is not set, the server SHOULD include all the qualifiers, including amended qualifiers, while this method creates or updates a CIM instance.
WBEM_FLAG_RETURN_IMMEDIATELY
0x00000010
If this bit is not set, the server MUST make the method call synchronously.
If this bit is set, the server MUST make the method call semisynchronously.
WBEM_FLAG_UPDATE_ONLY
0x00000001
The server MUST update a CIM instance pObject if the CIM instance is present.
This flag is mutually exclusive with WBEM_FLAG_CREATE_ONLY. If none of these flags are set, the server MUST create or update a CIM instance pObject.
WBEM_FLAG_CREATE_ONLY
0x00000002
The server MUST create a CIM instance pObject if the CIM instance is not already present.
pCtx: This parameter is optional. The pCtx parameter MUST be a pointer to an IWbemContext interface object. The pCtx parameter indicates whether the client is requesting a partial-instance update or a full-instance update. A partial-instance update modifies a subset of the CIM instance properties. In contrast, a full-instance update modifies all the properties. If NULL, this parameter indicates that the client application is requesting a full-instance update. When pCtx is used to perform a partial-instance update, the IWbemContext interface object MUST be filled in with the properties that are specified in the following table. If the IWbemContext interface object does not contain the properties in the table, the method MUST return WBEM_E_INVALID_CONTEXT.

Property name
Type
Description
__PUT_EXTENSIONS
VT_BOOL
If this property is set to TRUE, one or more of the other IWbemContext values have been specified. To perform a partial instance update, this property MUST be set to TRUE and the properties that follow MUST be set as specified in their respective descriptions.
__PUT_EXT_STRICT_NULLS
VT_BOOL
If this property is set to TRUE, the server MUST force the setting of properties to NULL. This parameter is optional.
__PUT_EXT_PROPERTIES
VT_ARRAY | VT_BSTR
Contains a CIM property list to update. The server MUST ignore the properties that are not listed. To perform a partial instance update, the list of properties MUST be specified.
__PUT_EXT_ATOMIC
VT_BOOL
If the return code indicates success, all CIM property updates MUST have been successful.
On failure, the server MUST revert any changes to the original state for all CIM property that was updated. On failure, not a single change MUST remain. The operation is successful when all properties are updated.
ppCallResult: If the input parameter is non-NULL, the server MUST return WBEM_S_NO_ERROR and IWbemCallResult MUST deliver the result of the requested operation (regardless whether WBEM_FLAG_RETURN_IMMEDIATELY is set). The output parameter MUST be filled according to the state of the lFlags parameter (whether WBEM_FLAG_RETURN_IMMEDIATELY is set) as listed in the following table.
-
Flag state
Operation Started Successfully
Operation Failed to Start
WBEM_FLAG_RETURN_IMMEDIATELY is not set.
MUST be set to IWbemCallResult if the input parameter is non-NULL.
MUST be set to NULL if the input parameter is non-NULL.
WBEM_FLAG_RETURN_IMMEDIATELY is set.
This parameter MUST NOT be NULL upon input. If NULL, the server MUST return WBEM_E_INVALID_PARAMETER. On output, the parameter MUST contain the IWbemCallResult interface pointer.
MUST be set to NULL if the input parameter is non-NULL.
-
If the ppCallResult input parameter is NULL and WBEM_FLAG_RETURN_IMMEDIATELY is not set, the server MUST deliver the result of the requested operation synchronously.
Return Values: This method MUST return an HRESULT value that MUST indicate the status of the method call. The server MUST return WBEM_S_NO_ERROR (specified in section 2.2.11) to indicate the successful completion of the method.
-
WBEM_S_NO_ERROR (0x00)
The security principal that makes the call MUST have WBEM_REMOTE_ENABLE and WBEM_ENABLE accesses to the namespace; otherwise, WBEM_E_ACCESS_DENIED MUST be returned.
If the CIM instance being updated is dynamic, the security principal that makes the call MUST have WBEM_WRITE_PROVIDER access to the namespace; otherwise, WBEM_E_ACCESS_DENIED MUST be returned.
If the CIM instance being created or updated is dynamic, the server MUST obtain SupportsPut for the corresponding provider in the ProviderTable. If SupportsPut is FALSE, the server MUST return WBEM_E_PROVIDER_NOT_CAPABLE.
If the CIM instance being updated is static and if the CIM instance is of a class that has a WMI system class as one of the classes in the parent hierarchy, the security principal that makes the call MUST have WBEM_FULL_WRITE access to the namespace; otherwise, WBEM_E_ACCESS_DENIED MUST be returned.
If the CIM instance being updated is static and if the CIM instance is of a class that does not have a WMI system class as one of the classes in the parent hierarchy, the security principal that makes the call MUST have WBEM_PARTIAL_WRITE_REP access to the namespace; otherwise, WBEM_E_ACCESS_DENIED MUST be returned.
If the CIM class of the instance being created has a parent class that is not abstract, the server MUST fail the operation with WBEM_E_NOT_FOUND. [DMTF-DSP0004] requires that the operation MUST succeed whenth e parent CIM class is abstract.
In response to the IWbemServices::PutInstance method, the server MUST evaluate the pInst parameter as specified in this section. It MUST add or update this instance into the current namespace. The method MUST fail if the following applies: if the server does not allow creation of new instances for the pInst class or does not allow modification of the instance that is represented by pInst; if the method parameters or their combinations are not valid as specified in this section; or if the server is unable to execute the method.
The successful synchronous method execution MUST return WBEM_S_NO_ERROR.
The semisynchronous method execution MUST follow the rules as specified in section 3.1.1.1.2.
The failed method execution MUST set output parameters to NULL and MUST return an error in the format that is specified in section 2.2.11.
The server SHOULD enforce a maximum length for the __RELPATH system property of the object pointed to by the pInst parameter, and return WBEM_E_QUOTA_VIOLATION if the limit is exceeded.<42>
