Sending pending messages
In situations of communication failure with the SiTef server, CliSiTef will automatically send any remaining data (e.g. commit, uncommit and undo data) only in the next POS transaction. However, it may take some time before the next transaction is initiated at the station. At times when the POS is at rest or “idle”, the automation can use the following routine to force the library to offload commit, uncommit, and undo messages to the SiTef server.
Upon return, the routine returns *0 if it managed to download all messages and non-zero if it occurs There is an error making it impossible to send them.
