DOCUMENT:Q114247 29-OCT-1999 [pcmail] TITLE :PC MAPI: Background on Common Messaging Calls (CMC) PRODUCT :Microsoft Mail For PC Networks PROD/VER:WINDOWS:3.0,3.2 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Mail for Windows, versions 3.0, 3.2 ------------------------------------------------------------------------------- Common Messaging Calls (CMC) is a client application programming interface (API) that provides functions to send and receive messages across a variety of computer platforms. CMC parallels the Simple MAPI function calls for functionality and the number of function calls. CMC applications work not only with Microsoft Mail, but also with Microsoft Mail services for Hewlett-Packard (HP) OpenMail, Banyan VINES, and AT&T EasyLink, as well as any other services that become available in the future such as for MS-DOS, Macintosh, OS/2, and VIM. CMC enables developers to use the same client interface on multiple platforms without the need for program modification. CMC currently functions under the Windows and Windows for Workgroups operating systems. It is not currently supported by Windows NT. MAPI version 1.0 will be shipped with CMC as the cross-platform mail-enablement API. You can obtain the official CMC specification by faxing a request to XAPIA at (408) 257-1478. There is no charge to developers or users who want to receive Microsoft CMC. The CMC SDK is currently available on the Microsoft Software Developer's Network (MSDN) CD (Level II).
