7、X.446 COMMON MESSAGING CALL API Summary This Recommendation specifies a simple call interface through which messaging-reliant applications may invoke the services of MHS across a standardized programming interface. The Recommendation was generated cooperatively with the XAPI Association and defines

8、the application programming interface being implemented for MHS by the worlds major vendors and service providers. Source ITU-T Recommendation X.446 was prepared by -T Study Group 7 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 9th of August 1997. Recommendation X.446

9、 (08197) 1 STD-ITU-T RECMN XP44b-ENGL 1797 D 4862573 Ob37829 53T FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommuni- cations. The IT Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is r

10、esponsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by

11、 the IT-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by ihe procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary st

12、andards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The IT draws attention to the possi

13、bility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of t

14、he Recommendation development process. As of the date of approval of this Recommendation, the ITU hadhad not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the lat

15、est information and are therefore strongly urged to consult the TSB patent database. O ITU 1997 All rights reserved.

39、833 Recommendation X.446 COMMON MESSAGING CALL API (Geneva, 1997) 1 Introduction This clause introduces the Common Messaging Call (CMC) Application Program Interface (API) and its specifications. It indicates the purpose of the interface, provides an overview of it, details abbreviations, provides d

40、ocument references, explains the level of abstraction of the interface, defines C naming conventions, and specifies conformance requirements. This Recommendation is an enhancement of the first version of the CMC MI, published in June 1993 by the X.400 MI Association. This Recommendation extends the

41、messaging-aware application support in the original document with support for messaging-reliant applications. 1.1 Purpose The purpose of this Recommendation is to specie a high-level messaging application program interface that can be supported by most messaging services deployed today. The API is i

42、ntended to enable application programmers to easily integrate messaging, and thus communications, into their applications, creating a large body of messaging-enabled applications. This Recommendation is directed toward messaging service developers who might wish to support such an application progra

43、m interface. This Recommendation may also guide application developers in understanding implementation-independent features of the Common Messaging Call APL The application developers must follow manuals provided by the system they are using for messaging support. 1.2 Overview The Common Messaging C

44、all Application Program Interface provides a set of high-level functions for messaging-enabled applications to send and receive electronic messages. Within the range of messaging-enabled applications, there are messaging-aware applications and messaging-reliant applications. Messaging-aware applicat

45、ions are those that can function quite satisfactorily as stand-alone applications, but which might connect to a messaging service to provide enhanced functionality. An example would be a word processing or spreadsheet application that has the capability to send the document or file using a FILE-SEND

46、 option off of the menu. Messaging-reliant applications are those which are inherently dependent on the existence of a messaging service to carry out their functionality. Examples of these are Electronic Data Interchange (EDI), information distribution applications, conferencinglcollaboration applic

47、ations, and possibly some distributed databases. This interface is designed to be independent of the actual messaging protocol employed between sender and recipient. The interface will support the creation and reception of standard message formats such as X.400 and SMTPNIME (RFC 822RFC 1521) as well

48、 as proprietary message formats. This is achieved through generic definition of capabilities common to most messaging protocols, plus a mechanism for defining extensions, which can be used to invoke protocol-specific services. The interface is also designed to be independent of the operating system

49、and underlying hardware used by the messaging service. Recommendation X.446 (08/97) 1 Another important consideration in the design of this API is to enable simple application actions to be taken with a minimum number of function calls while allowing more complex actions to be possible as well. To achieve these often conflicting objectives, the CMC AFI has two interfaces: a Simple CMC interface and a Full CMC interface. The Simple CMC interface provides a minimum number of function calls needed to send or receive a message by messaging-aware applications. The Full CMC
