Parameters

    [in] Interface identifier (IID) of the call context that is being requested. If you are using the default call context supported by standard marshaling, IID_IServerSecurity is available. For COM+ applications using role-based security, IID_ISecurityCallContext is available.

    [out] Address of pointer variable that receives the interface pointer requested in riid. Upon successful return, *ppInterface contains the requested interface pointer.

Return Value

  • E_NOINTERFACE

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. This is one of the functions provided to give the server access to any contextual information of the caller.
