Routine Description:

    This function is used to for Windows components to get 
    component policy value.
    
Arguments:

    pwszValueName
        The name of the requested value.
        
    peDataType
        Data type. Following types are supported:
            SL_DATA_SZ     - UNICODE string
            SL_DATA_DWORD  - DWORD
            SL_DATA_BINARY - Binary blob
        
    pcbValue
        Size of the allocated buffer.
        
    ppbValue
        The value. If successful, the data is returned in the buffer 
        allocated by SLC.
        The caller has to call SLFreeMemory to free the memory.

/*++
Routine Description:

    Determines if an installation is a Genuine Windows installation.
    It interrogates the license for pAppId and inspects the "Tampered"
    flag.  If either the license for pAppId is invalid or the "Tampered"
    flag is set, the installation is assumed to be invalid.

    pGenuineState is ONLY modified if the result is S_OK.  Otherwise, it is
    left in the state in which it was found on function entry.

Arguments:

    pAppId
        Application identifier. 

    pbGenuineState
        Output state value - one of the SL_GENUINE_STATE values

    pUIOptions
        Non genuine UI options. If NULL, no UI is displayed if 
        state is non-genuine. 

Return Error:

    S_OK
        Operation completed successfully.

    E_INVALIDARG
        pGenuineState is NULL.

Routine Description:

    Returns genuine ticket acquired from Software Licensing Server based
    on SLWGA template blob. 
    
    The client is responsible for freeing the buffer returned in ppGenuineBlob.
    SLWGAFreeMemory should be used to free the memory.

    The output parameters are only set if the function returns S_OK.  Otherwise,
    they are left as they were when the function was entered.

Arguments:

    ppTicketBlob
        Pointer to output pointer to be returned (XrML genuine ticket).

    pcbTicketBlob
        An output pointer that will contain the size, in bytes, of the region
        returned in ppTicketBlob.

    pwszTemplateId
        Id of genuine blob template kept on the server side. 

    pwszServerUrl
        Ticket acquisition server url. 

    pwszClientToken
        Client custom token.
