pSOSystem System Calls - Read

6 pROBE+ and ESp
System Calls
This chapter provides detailed descriptions of the system calls supported by
pROBE+ and ESp. 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, and its return value.
The ESp cross-system visual analyzer graphically displays your embedded
application’s activity on a host terminal and allows you to analyze the application’s
performance. ESp accepts one system call, log_event(), through its targetresident
application monitor, pMONT.
pROBE+ is pSOSystem’s target debugger and analyzer. pROBE+ accepts two system
calls: db_input() and db_output().
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 gives the pSOSystem calls that are associated with each
one.
