2 RealCT Direct API Developer Guide
Chapter 1: Architecture
How RealCT Interfaces With Your System
Interfacing With Windows Platforms
The Win32 Application Programming Interface (API) provides a
set of functions and defines how those functions behave.
Microsoft provides two platforms that support the Win32 API:
Windows NT and Windows 2000. Since each of these platforms
support a common set of Win32 API functions, you can write one
application for all platforms. However, the three platforms
implement functions differently and to different degrees.
Windows NT Windows NT supports the full functionality of the Win32 API.
This full support means that Windows NT applications are
robust and fast. Windows NT can also run on machines with
different CPUs such as MIPS R4000, a DEC alpha, or
Motorola’s PowerPC.
Windows 2000 To be supplied.
Header File To interface to the Brooktrout Direct device manager library,
your application must include the following header file:
“brktddm.h”
This header file also includes other header files that define
function tags, data structures, parameter values, and error
values for the device drivers.
Library You must compile and link your application program with the
RealCT Direct Device Manager (DDM) library. Brooktrout
recommends using the Microsoft C/C++ compiler, versions 6.0
and later, for the RealCT Direct API. The library file is:
brktddm.lib
Note:
Ensure that you have installed the brktddm.dll file
during the installation process.
