OSS File-System Components
OSS File-System Components
The software components that work together to provide access to an OSS file are
shown in Figure 1-4 on page 1-10. Many of these components are configured and
managed using the interfaces described in this guide.
An application running in the OSS environment makes calls for access to an OSS file
through function calls in the OSS file-system library. The OSS file-system library is
present in each processor. The library consists of functions in a shared run-time library
(SRL) and in the system library. OSS file-system library functions are described in the
Figure 1-4. OSS File-System Components
