Remarks

CoGetCallContext retrieves the context of the current call on the current thread. The riid parameter specifies the interface on the context to be retrieved. Currently, only IServerSecurity_P_YLT is available from the default call context supported by standard marshaling.

This is one of the functions provided to give the server access to any contextual information of the caller and to encapsulate common sequences of security checking and caller impersonation.
