PPC Start Session (Macintosh)

Starts a PPC session with an application through a port. If a timeout occurs or the VI aborts before running, the port closes.

timeout ticks, if non-zero, indicates the number of ticks the PPC Inform Session VI waits for LabVIEW to establish a session. After timeout ticks, LabVIEW returns the errTimedOut error. One tick equals 1/60 of a second. The default is 0, which indicates no timeout. Refer to PPC Inform Session for more information.
port refnum is a refnum that uniquely indicates the port through which LabVIEW attempts to start a session with the application.
target ID describes the target application and its location.
user data is an application-defined value that the VI sends with the request for a session. The default is 0.
If Allow Dialog is TRUE (default), the VI displays the User Identity Dialog Box if the target application requires authorization.
prompt appears in the dialog box.
session refnum is a session refnum, which you use in subsequent communication for this session.
reject info contains an application-defined number if the target application rejects the request.
error, if negative, indicates a Macintosh error. If positive, error indicates an error internal to the CIN that generated it. Refer to the PPC Error Codes for a list of PPC error codes and their descriptions.
