pSOSystem System Calls - Read

Using This Manual
This manual is part of a documentation set that describes pSOSystem, the modular,
high-performance real-time operating system environment from Integrated Systems,
Inc. This manual is targeted for embedded application developers using the pSOSystem
environment. Basic familiarity with UNIX terms and concepts is assumed.
System Calls contains detailed descriptions of all pSOSystem system calls and error
codes. For purpose of usability, System Calls provides two appendices:
■ Appendix A provides an alphabetical list of all system calls with a summary description
of each call and a reference to the page where you will find call details.
This enables you to search for a call by function when you do not have the specific
call name.
■ Appendix B provides a numerical list of all error codes returned by pSOSystem.
Each error code is listed with its description and the system calls that can return
it.
System Calls and other manuals comprise the basic documentation set for the pSO-
System operating system. These other manuals are the pSOSystem Getting Started,
pSOSystem System Concepts, pSOSystem Programmer’s Reference, pSOSystem Advanced
Topics, and the pSOSystem Application Examples.
