Microsoft Developer Studio Visual C/C++ (5.0,6.0) can be used as a development environment. This approach avoids the extra costs involved in introducing a proprietary development environment. Wizards for fast code generation are also available.

The INtime and iRMX III APIs provide very well defined and structured interfaces to the operating system .

INtime is based on field-proven iRMX kernel technology. The INtime API  consists of two parts. They contain all system calls for the real-time kernel (RT-Calls) and Win32 system calls (NTX-Calls) for communication between INtime and Windows. they provide hard real-time operation and are modeled on the Win32 API.  The NTX API is a standard Win32 DLL-based C programming interface. It co-ordinates communication between NT and RT applications.

iRMX III is a stand-alone operating system and is highly configurable - from a small-footprint, kernel-only solution to a full-service, hard real-time operating system. It is designed using a layered approach. Here we summarise the iRMX API, which offers a broad range of real-time, object-based functions and features.
