The QNX Neutrino System Analysis Toolkit User's Guide describes how to use the instrumented microkernel to obtain a detailed analysis of what's happening in an entire QNX Neutrino system. This guide contains the following sections and chapters:
|To find out about:||Go to:|
|What the SAT is, what it can do for you, and how it works||Introduction|
|What generates events||Events and the Kernel|
|How the kernel buffers data||Kernel Buffer Management|
|How to save data||Capturing Trace Data|
|Different ways to reduce the amount of data||Filtering|
|What the data tells you||Interpreting Trace Data|
|Examples of filtering the trace data||Tutorials|
|Sample data-capture and parsing programs||Sample Programs|
|What specific events return||Current Trace Events and Data|
Throughout this manual, we use certain typographical conventions to distinguish technical terms. In general, the conventions we use conform to those found in IEEE POSIX publications. The following table summarizes our conventions:
|Code examples||if( stream == NULL )|
|File and pathnames||/dev/null|
|Keyboard input||something you type|
|Programming data types||unsigned short|
|Programming literals||0xFF, "message string"|
We use an arrow (→) in directions for accessing menu items, like this:
You'll find the Other... menu item under.
We use notes, cautions, and warnings to highlight important messages:
|Notes point out something important or useful.|
|Cautions tell you about commands or procedures that may have unwanted or undesirable side effects.|
|Warnings tell you about commands or procedures that could be dangerous to your files, your hardware, or even yourself.|
In our documentation, we use a forward slash (/) as a delimiter in all pathnames, including those pointing to Windows files.
We also generally follow POSIX/UNIX filesystem conventions.
