【国外标准】 IEEE Standard for Information Technology, OSI Application Program Interfaces--File Transfer, Access, and Management [C Language]

This standard defines an application program interface (API) to the services of the OSI File Transfer, Access, and Management (FTAM) application-service-element. The API provides access to a set of high-level operations. That is, API functions map on to a sequence of FTAM primitives that implement the required operation. Apart from association management functions, functions that map directly onto FTAM service primitives are not provided. The API provides file transfer and file management… read more operations. File access and filestore management operations are not provided. The API supports the FTAM initiator role. The FTAM responder role is not supported. The API supports a context-free mode of operation (where the operation is performed using an FTAM association that is created specifically for the operation and destroyed once the operation is completed) and a context-sensitive mode of operation (where the FTAM association is created and destroyed independently, and operations are performed within the context of this independent association). In order to support the context-sensitive mode of operation, the API defines a set of association management functions that create and destroy FTAM associations. An implementation conforming to this standard requires support of an implementation of the services defined in IEEE Std 1224-1993 {14}. This standard is a "thick" C binding (that is, it defines both the semantics of the operations and the C language binding to those semantics). An understanding of FTAM is assumed in the remaining parts of this specification. Those unfamiliar with FTAM may wish to read Annex , Overview of FTAM (and perhaps Annex , Overview of OM) before proceeding with the remainder of this standard. read less
