| Argument | Type | Description |
| pdwDestCtx | DWORD * | The place at which the destination context is to be returned. |
| ppvDestCtx | void ** | May be NULL. If non-NULL, then this is the place at which auxiliary information associated with certain destination contexts will be returned. Interface proxies may not hold on to this returned pointer in their internal state; rather, they must assume that a subsequent call to IRpcChannel::Call() may in fact invalidate a previously returned destination context.12. |
| return value | HRESULT | S_OK, E_OUTOFMEMORY, E_UNEXPECTED, but no others. |
