DrtOpen function (drt.h)
The DrtOpen function creates a local Distributed Routing Table instance against criteria specified by the DRT_SETTINGS structure.
HRESULT DrtOpen( const DRT_SETTINGS *pSettings, HANDLE hEvent, const PVOID pvContext, HDRT *phDrt );
Pointer to the DRT_SETTINGS structure which specifies the settings used for the creation of the DRT instance.
