About the RTX Programming Interfaces

RTX provides an essential set of real-time programming interfaces in the Win32 environment. The RTX interfaces are compatible with the Win32 programming interfaces. In addition, RTX provides extensions to Win32 in order to provide a complete set of real-time functions to the application programmer.

RTX application programs can use the real-time extensions in both the Win32 and RTSS environments and programs can use the Win32-supported API in the real-time subsystem (RTSS) environment. This provides maximum flexibility to the developer. In the Win32 environment, programs can be developed and tested with the real-time extensions using the vast number of Win32 development tools. The same program can be re-linked as an RTSS program and run deterministically.

The application programming interface for RTX is composed of three sets of interfaces:

Real-Time API (RTAPI)
Win32-Supported API
C Run-Time Library-Supported API
C++ Library-Supported API
