ICondition::GetSubConditions method (structuredquerycondition.h)
Retrieves a collection of the subconditions of the search condition node and the IID of the interface for enumerating the collection.
Syntax
HRESULT GetSubConditions(
[in] REFIID riid,
[out, retval] void **ppv
);
Parameters
[in] riid
Type: REFIID
The desired IID of the enumerating interface: either IID_IEnumUnknown, IID_IEnumVARIANT or (for a negation condition) IID_ICondition.
[out, retval] ppv
Type: void**
Receives a collection of zero or more ICondition objects. Each object is a subcondition of this condition node. If riid was IID_ICondition and this is a negation condition, this parameter receives the single subcondition.
Return value
Type: HRESULT
Returns S_OK if successful, E_FAIL if this is a leaf node, or an error value otherwise.
Remarks
The riid parameter must be the GUID of an IEnumUnknown or IEnumVARIANT interface or in the case of a negation node, IID_ICondition.
If the subcondition is a negation node, ppv is set to an enumeration of one element.
If the node is a conjunction or disjunction node, ppv is set to an enumeration of the subconditions.
