Basic Operation

Initial step

Initially, Commercial Automation must execute the command
ConfiguraIntSiTefInterativo, passing the necessary information to
so that the Sales Terminal can communicate with SiTef, such as Address
SiTef IP, Company Code (in SiTef Demo this code is
00000000) and the terminal identification.

This function should only be called when CliSiTef is
loaded i.e. it is not necessary to call it with each new transaction (unless there is a specific need to change
company parameters, terminal or SiTef server IP).

The routine returns a value indicating whether the configuration occurred with
success or not. If 0 (zero) returns, the process occurred in a
correct.

Transaction itself

The next step is then to call the IniciaFuncaoSiTefInterativo function,
passing the described parameters to it.

Upon return, it returns the value 10000 to continue the transaction
or other value to close.

If the return is 10000, you must call the function
ContinuaFuncaoSiTefInterativo, with the parameters also described for
her we next topics.

While CliSiTef returns the value when calling this function
10000, the automation must keep repeating the call to this function
as many times as necessary until the return value of the function
be 0 (zero), indicating that everything went well, or different from 0
and 10000 indicating that an abnormal interruption occurred.

Confirmation (or non-confirmation) of the transaction

If the return was 0 (zero), the automation closes the loop and if there was
TEF coupon printing, the automation must print them and call another
function, the FinalizaFuncaoSiTefInterativo, confirming or not the
transaction depending, respectively, on whether the coupon was printed
correctly or not.

If the return was different from 10000 and 0 then the automation
simply exits the loop and, at the programmer's option, may or may not display
a message according to the return of the called function. For example, if
returned -2, it means that the transaction was canceled by the operator.
These negative returns are described in this document.

Graphically exemplifying the flow described in this topic, we would have the
