03/09/2018

Loads a specified protocol manager and retrieves an interface for that protocol manager.

Syntax

virtual HRESULT LoadProtocolManagerAndGetCustomInterface(  
   IN PCWSTR pProtocolManagerDll,  
   IN PCWSTR pProtocolManagerDllInitFunction,  
   IN DWORD dwCustomInterfaceId,  
   OUT PVOID* ppCustomInterface  
) = 0;

Parameters

pProtocolManagerDll
The DLL for the protocol manager to load.

pProtocolManagerDllInitFunction
The DLL entry point for the protocol manager.

dwCustomInterfaceId
The interface to return for the protocol manager.

ppCustomInterface
A pointer to a buffer that will receive the interface specified by dwCustomInterfaceId.

Return Value

An HRESULT. Possible values include, but are not limited to, those in the following table.

Value	Description
S_OK	Indicates that the operation was successful.
ERROR_FILE_NOT_FOUND	Indicates that the protocol manager specified by `pProtocolManagerDll` does not exist, or that the DLL entry point specified by `pProtocolManagerDllInitFunction` is not valid.
ERROR_INVALID_PARAMETER	Indicates that the interface specified by `dwCustomInterfaceId` is not valid.

Remarks

The LoadProtocolManagerAndGetCustomInterface method allows one protocol manager to take advantage of functionality that is implemented in another protocol manager. You can load only a subset of protocol manager interfaces by using this method, because most interaction with protocol managers is completed through the worker process framework.

When you no longer need the interface, release it before you call the protocol manger's IProtocolManager::Shutdown method.
