Title:  STB Editor's Introduction
-------------------------------------------------------------------------------

STB Overview
------------

This month's STB contains articles of general interest in the topics outlined
below.


** SunOS

"Realtime Scheduling in SunOS 5.0" is a reprint, with updates and corrections,
of a SunSoft USENIX technical paper, describing the fundmental mechanisms in
Solaris 2.x to provide realtime scheduling functionality. The paper discusses
threads and their synchronization objects; various priority values, priority
inheritance, and the priority inversion problem; and scheduling attributes,
including new scheduling interfaces.

** Languages

This month, we reproduce three chapters from the SunPro manual on the
SPARCworks product, "Introduction to SPARCworks."

"SPARCworks and the Software Development Cycle" introduces the SPARCworks suite
of development tools (SPARCworks Manager, SourceBrowser, Debugger, Analyzer,
FileMerge, and MakeTool) and describes their use in the development and
maintenance of application software. "SPARCworks Manager" examines the tool
that manages the entire suite of tools, and "SourceBrowser" details the
SPARCworks tool that assists the developer in statically analyzing source code.
