INSSEventAuthorization::GetAuthorizedEvents

INSSEventAuthorization::GetAuthorizedEvents

Used to specify which events must be authorized before they can be performed.

Syntax

HRESULT GetAuthorizedEvents (
DWORD cMaxAuthorizedEvents,
DWORD *pcAuthorizedEvents,
NSS_EVENT_TYPE *rgAuthorizedEvents
);

Parameters

[in] cMaxAuthorizedEvents

Indicates the maximum number of events that can be specified for authorization.

[out] pcAuthorizedEvents

Specifies the number of authorization events that are set by the component.

[out] rgAuthorizedEvents

Specifies the list of events that require authorization. Each event specified by this parameter triggers a call from the server to the INSSEventAuthorization::AuthorizeEvent method of the component. The following values are supported for this parameter.

Event type	Description
NSSE_CONNECT	Client requests a connection.
NSSE_OPEN	Client requests that a title be opened.
NSSE_PLAY	Client requests that streaming of a title be started.
NSSE_SKIP_AUTHENTICATION	Client requires user authentication.

Return Values

This method must return S_OK upon successful completion, or an HRESULT error value.

Remarks

Memory for the events specified by the rgAuthorizedEvents parameter is allocated and freed by the server.

The following code illustrates a skeletal implementation of the INSSEventAuthorization::GetAuthorizedEvents method:

HRESULT
CEventNotification::GetAuthorizedEvents( 
    DWORD cMaxAuthorizedEvents,
    DWORD __RPC_FAR *pcAuthorizedEvents,
    NSS_EVENT_TYPE __RPC_FAR *rgAuthorizedEvents ) 
{
  if ( ( NULL == rgAuthorizedEvents )
    || ( NULL == pcAuthorizedEvents )
    || ( cMaxAuthorizedEvents < 3 ) )
  {
    return( E_INVALIDARG );
  }
  *pcAuthorizedEvents = 3;
  rgAuthorizedEvents[0] = NSSE_CONNECT;
  rgAuthorizedEvents[1] = NSSE_OPEN;
  rgAuthorizedEvents[2] = NSSE_PLAY;
  return(S_OK);
};
