2021-09-15

Enumerates all interfaces implemented by the specified TypeDef.

Syntax

HRESULT EnumInterfaceImpls (  
   [in, out]  HCORENUM       *phEnum,
   [in]   mdTypeDef          td,  
   [out]  mdInterfaceImpl    rImpls[],
   [in]   ULONG              cMax,  
   [out]  ULONG*             pcImpls  
);

Parameters

phEnum
[in, out] A pointer to the enumerator.

td
[in] The token of the TypeDef whose MethodDef tokens representing interface implementations are to be enumerated.

rImpls
[out] The array used to store the MethodDef tokens.

cMax
[in] The maximum length of the rImpls array.

pcImpls
[out] The actual number of tokens returned in rImpls.

Return Value

HRESULT	Description
`S_OK`	`EnumInterfaceImpls` returned successfully.
`S_FALSE`	There are no MethodDef tokens to enumerate. In that case, `pcImpls` is set to zero.

Remarks

The enumeration returns a collection of mdInterfaceImpl tokens for each interface implemented by the specified TypeDef. Interface tokens are returned in the order the interfaces were specified (through DefineTypeDef or SetTypeDefProps). Properties of the returned mdInterfaceImpl tokens can be queried using GetInterfaceImplProps.
