pSOSystem System Calls - Read

1 pSOS+ System Calls
This chapter provides detailed information on each system call in the pSOS+
component of pSOSystem. The calls are listed alphabetically, with a multipage
section of information for each call. Each call’s section includes its syntax, a
detailed description, its arguments, its return value, and any error codes that it can
return. In addition, it includes information specific to certain processors if such
information is needed.
Where applicable, the section also includes the headings “Notes” and “See Also.” The
“Notes” entry provides important information not specifically related to the call
description. In particular, it identifies how the pSOS+m kernel handles the call if
multiple processors are involved (see “Multiprocessor Considerations,”) and
indicates where the call can be made. “See Also” lists other system calls that have
related information.
If you need to look up a system call by its functionality, refer to Appendix A, “Tables
of System Calls,” which lists the calls alphabetically by component and provides a
brief description of each call.
For more information on error codes, refer to Appendix B, “Error Codes,” which lists
the codes numerically and shows which pSOSystem calls are associated with each
one.
