rtapi − Introduction to the RTAPI API |
|
RTAPI is a library providing a uniform API for several real time operating systems. As of ver 2.1, RTLinux, RTAI, and a pure userspace simulator are supported. The file rtapi.h defines the RTAPI for both realtime and non-realtime code. This is a change from Rev 2, where the non-realtime (user space) API was defined in ulapi.h and used different function names. The symbols RTAPI and ULAPI are used to determine which mode is being compiled, RTAPI for realtime and ULAPI for non-realtime. |
