SHAssocEnumHandlersForProtocolByApplication function
Gets an enumeration interface that provides access to handlers associated with a given protocol.
Syntax
HRESULT SHAssocEnumHandlersForProtocolByApplication(
_In_ PCWSTR protocol,
_In_ REFIID riid,
_Out_ void **enumHandlers
);
Parameters
- protocol [in]
-
Type: PCWSTR
Pointer to a string that specifies the protocol.
- riid [in]
-
Type: REFIID
A reference to the IID of the interface to retrieve through enumHandlers, typically IID_IEnumAssocHandlers.
- enumHandlers [out]
-
Type: void**
When this method returns, contains the interface pointer requested in riid. This is typically IEnumAssocHandlers.
Return value
Type: HRESULT
If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
It is recommended that you use the IID_PPV_ARGS macro, defined in Objbase.h, to package the riid and enumHandlers parameters. This macro provides the correct IID based on the interface pointed to by the value in enumHandlers, which eliminates the possibility of a coding error.
