Asynchronous status call, with notification by message (ECI_STATE_ASYNC_MSG)

This call type is available only for programs running on Windows®.

eci_message_qualifier can be used as an input to provide a user-defined name for the call.

The ECI sends a notification message to the specified window when the response is available. (For details of the message format, see Reply message formats.) On receipt of this notification, the calling application should use ECI_GET_SPECIFIC_REPLY to receive the actual response.

For details of the additional parameters relating to notification by message, see the description of the ECI_ASYNC_NOTIFY_MSG call type.
