<h1>Debug information</h1>
|
|
|
|
<p>The <b>Debug</b> perspective lets you manage the debugging or running of a program
|
|
in the Workbench. You can control the execution of your program by setting
|
|
breakpoints, suspending launched programs, stepping through your code, and
|
|
examining the contents of variables.</p>
|
|
<p> The <b>Debug</b> perspective displays the following information:</p>
|
|
|
|
<ul>
|
|
<li>The stack frame for the suspended threads
|
|
for each target that you are debugging</li>
|
|
<li>Each thread in your program represented as a node in the tree</li>
|
|
<li>The process for each program that you are running</li>
|
|
</ul>
|
|
<p>The <b>Debug</b> perspective also drives the <b>C/C++ Editor</b>. As you step
|
|
through your program, the <b>C/C++ Editor</b> highlights the location of the
|
|
execution pointer. </p>
|
|
|
|
<h2>Variables</h2>
|
|
|
|
<p>You can view information about the variables in a selected stack frame in the
|
|
Variables view. When execution stops, the changed values are
|
|
by default highlighted in red. Like the other debug-related views, the Variables view does
|
|
not refresh as you run your executable. A refresh occurs when execution stops.</p>
|
|
|
|
<h2>Expressions</h2>
|
|
|
|
<p>An expression is a snippet of code that can be evaluated to produce a result.
|
|
The context for an expression depends on the particular debug model. Some
|
|
expressions may need to be evaluated at a specific location in the program so
|
|
that the variables can be referenced. You can view information about expressions
|
|
in the Expressions view.</p>
|
|
|
|
<h2>Registers</h2>
|
|
|
|
<p>You can view information about the registers in a selected stack frame.
|
|
Values that have changed are highlighted in the Registers view when your program
|
|
stops.</p>
|
|
|
|
<h2>Memory</h2>
|
|
|
|
<p>You can inspect and change your process memory.</p>
|
|
|
|
<h2>Shared libraries</h2>
|
|
|
|
<p>You can view information about the shared libraries loaded in the current
|
|
debug session.</p>
|
|
|
|
<h2>Signals</h2>
|
|
|
|
<p>You can view the signals defined on the selected debug target and how the
|
|
debugger handles each one.</p>
