Using SWID as a Server
5. Close the SWID process to signal the end of startup.
Using SWID as a Server
1. Start the SWID process.
2. Call the WRITEREAD procedure when the fingerprint is required.
The WRITE buffer must contain one of the commands described next. The reply from
the SWID server is returned in the READ buffer. The
countread parameter advises
you of the total reply size. The reply contains one or more FO-REC records described
under Formatted Output on page 5-1.
3. Close the SWID process to terminate the server when it is no longer required.
The write buffer of a WRITEREAD can contain only one of the following commands:
•
WhoRU
•
GetFpts
•
GetFpts2
•
GetOrigFpts
•
DisplayStatistics
WhoRU Command
An application that uses SWID as a server process uses this command to determine
the product version of the SWID process. The command structure contains two words
and SWID requires that the
rectype word has the value 7006.
You should pass the desired value in the ExpectedVersion field to indicate what
product version of SWID you are anticipating. For SWID product versions T9298AAI
Note. When sending the startup message, applications should ignore error 70 returned by
SWID. Error 70 indicates that the server is now ready to receive more messages (such as
parameters) as part of the startup.
