Changes to C-Header file11Page 3CWA 14050-24:2000ForewordThis CWA is revision 3.0 of the XFS interface specification.The move from an XFS 2.0 specificati
11、on (CWA 13449) to a 3.0 specification has been prompted by a series offactors.Initially, there has been a technical imperative to extend the scope of the existing specification of the XFS Managerto include new devices, such as the Card Embossing Unit.Similarly, there has also been pressure, through
12、implementation experience and the advance of the Microsofttechnology, to extend the functionality and capabilities of the existing devices covered by the specification.Finally, it is also clear that our customers and the market are asking for an update to a specification, which is nowover 2 years ol
13、d. Increasing market acceptance and the need to meet this demand is driving the Workshop towardsthis release.The clear direction of the CEN/ISSS XFS Workshop, therefore, is the delivery of a new Release 3.0 specificationbased on a C API. It will be delivered with the promise of the protection of tec
14、hnical investment for existingapplications and the design to safeguard future developments.The CEN/ISSS XFS Workshop gathers suppliers as well as banks and other financial service companies. A list ofcompanies participating in this Workshop and in support of this CWA is available from the CEN/ISSS S
15、ecretariat.This CWA was formally approved by the XFS Workshop meeting on 2000-10-18. The specification is continuouslyreviewed and commented in the CEN/ISSS Workshop on XFS. It is therefore expected that an update of thespecification will be published in due time as a CWA, superseding this revision
