Messaging Application Programming Interface
<messaging> (MAPI) A messaging architecture and a client interface
component for applications such as electronic mail, scheduling, calendaring and
document management. As a messaging architecture, MAPI provides a consistent
interface for multiple application programs to interact with multiple messaging
systems across a variety of hardware platforms.
MAPI provides better performance and control than Simple MAPI, Common Messaging
Calls (CMC) or the Active Messaging Library. It has a comprehensive, open,
dual-purpose interface, integrated with Microsoft Windows. MAPI can be used by
all levels and types of client application and "service providers" - driver-like
components that provide a MAPI interface to a specific messaging system. For
example, a word processor can send documents and a workgroup application can
share and store different types of data using MAPI.
MAPI separates the programming interfaces used by the client applications and
the service providers. Every component works with a common, Microsoft
Windows-based user interface. For example, a single messaging client application
can be used to receive messages from fax, a bulletin board system, a host-based
messaging system and a LAN-based system. Messages from all of these systems can
be delivered to a single "universal Inbox".
MAPI is aimed at the powerful, new market of workgroup applications that
communicate with such different messaging systems as fax, DEC All-In-1, voice
mail and public communications services such as AT&T Easylink Services,
CompuServe and MCI MAIL. Because workgroup applications demand more of their
messaging systems, MAPI offers much more than basic messaging in the programming
interface and supports more than local area network (LAN)-based messaging
systems. Applications can, for example, format text for a single message with a
variety of fonts and present to their users a customised view of messages that
have been filtered, sorted or preprocessed.
MAPI is built into Windows 95 and Windows NT and can be used by 16-bit and
32-bit Windows applications. The programming interface and subsystem contained
in the MAPI DLL provide objects which conform to the Component Object Model.
MAPI includes standard messaging client applications that demonstrate different
levels of messaging support.
MAPI provides cross platform support through such industry standards as SMTP,
X.400 and Common Messaging Calls. MAPI is the messaging component of Windows
Open Services Architecture (WOSA).
