NAME
SHWeakQueryInterface (SHLWAPI.267)SYNOPSIS
HRESULT SHWeakQueryInterface(
IUnknown* pUnk,
IUnknown* pInner,
IID* riid,
LPVOID* ppv
)
PARAMS
pUnk [In] Outer object.pInner [In] Inner object.
riid [In] Interface GUID to query for.
ppv [Out] Destination for queried interface.
DESCRIPTION
Get an interface from an object.
RETURNS
Success: S_OK. ppv contains the requested interface.
Failure: An HRESULT error code.
NOTES
This QueryInterface asks the inner object for an interface. In case of aggregation this request would be forwarded by the inner to the outer object. This function asks the inner object directly for the interface circumventing the forwarding to the outer object.
IMPLEMENTATION
Exported by ordinal only. Use GetProcAddress(3w) to obtain a pointer to the function.
Implemented in "dlls/shlwapi/ordinal.c".
Debug channel "shell".
