Asynchronous program link call, with notification by message (ECI_ASYNC_NOTIFY_MSG)

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

The calling application gets control back when the ECI accepts the request. Note that this does not indicate that the program has started to run, merely that the parameters have been validated. The request might be queued for later processing.

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. The ECI_GET_REPLY call type is deprecated.

The following fields are required parameters for notification by message:

eci_message_qualifier can be used as an input to provide a user-defined name for the call. It is returned as part of the notification message for the Windows environment.
