No, in EPICS it's the Operating System Independent layer, part of EPICS
Base which provides implementations of some standardized APIs on the
different operating systems we run on. In Matt's case they had to modify
some EPICS drivers to call our OSI APIs instead of the original VxWorks
ones for talking to VMEbus slave devices, and the resulting source files
can then be compiled for VxWorks, RTEMS and even Linux with no source
changes or conditional compilation.
