This method returns a pointer to the ITypeInfointerface for the object's type information. The type information for an object corresponds to the object's coclassentry in a type library.
Syntax
HRESULT GetClassInfo( ITypeInfo** ppTI ); |
Parameters
- ppTI
-
[out] Address of ITypeInfo*pointer variable that receives the interface pointer to the object's type information.
The caller is responsible for calling the ITypeInfo::Releasemethod on the returned interface pointer if this method returns successfully.
Return Value
This method supports the standard return values E_OUTOFMEMORY and E_UNEXPECTED.
If the type information was successfully returned, the method returns S_OK.
If the address in ppTIis not valid, the method returns E_POINTER.
Remarks
Notes to Callers
The caller is responsible for calling ITypeInfo::Releasewhen the returned interface pointer is no longer needed.
Notes to Implementers
This method must call ITypeInfo::AddRefbefore returning. If the object loads the type information from a type library, the type library itself will call AddRefin creating the pointer.
Because the caller cannot specify a locale identifier (LCID) when calling this method, this method must assume the neutral language, that is, LANGID_NEUTRAL, and use this value to determine what locale-specific type information to return.
This method must be implemented; E_NOTIMPL is not an acceptable return value.
