//
//  Description:
//      Sends an authentication request to a remote device. 
//
//      There are two modes of operation. "Wizard mode" and "Blind mode."
//
//      "Wizard mode" is invoked when the pszPasskey is NULL. This will cause
//      the "Bluetooth Connection Wizard" to be invoked. The user will be
//      prompted to enter a passkey during the wizard after which the
//      authentication request will be sent. The user will see the success
//      or failure of the authentication attempt. The user will also be
//      given the oppurtunity to try to fix a failed authentication.
//
//      "Blind mode" is invoked when the pszPasskey is non-NULL. This will
//      cause the computer to send a authentication request to the remote
//      device. No UI is ever displayed. The Bluetooth status code will be
//      mapped to a Win32 Error code.
//
//  Parameters:
//
//      hwndParent
//          The window to parent the authentication wizard. If NULL, the 
//          wizard will be parented off the desktop.

//          succeed.
//
//      pbtdi
//          BLUETOOTH_DEVICE_INFO record of the device to be authenticated.
//
//      pszPasskey
//          PIN to be used to authenticate the device.  If NULL, then UI is
//          displayed and the user steps through the authentication process.
//          If not NULL, no UI is shown.  The passkey is NOT NULL terminated.
//

// Description:
//      Iterates over a container stream, returning each elemetn contained with

//
// Parameters:
//      IN pContainerStream
//          pointer to valid SDP stream whose first element is either a sequence
//          or alternative
//
//      IN cbContainerlength
//          length in bytes of pContainerStream
//
//      IN OUT pElement
//          Value used to keep track of location within the stream.  The first
//          time this function is called for a particular container, *pElement
//          should equal NULL.  Upon subsequent calls, the value should be

//      ERROR_SUCCESS
//          The call succeeded, pData contains the data
//
//      ERROR_NO_MORE_ITEMS
//          There are no more items in the list, the caller should cease calling

//
//      ERROR_INVALID_PARAMETER
//          A required pointer is NULL or the container is not a valid SDP
