<h1>Adding watchpoints</h1>
|
|
|
|
<p>A watchpoint is a special breakpoint that stops the execution of an
|
|
application whenever the value of a given expression changes, without specifying
|
|
where this may happen. Unlike breakpoints which are line-specific watchpoints
|
|
are associated with files. They take effect whenever a specified condition is
|
|
true regardless of when or where it occurred.</p>
|
|
|
|
<p>To add a watchpoint:</p>
|
|
|
|
<ol>
|
|
<li>Click <b>Run > Add C/C++ Watchpoint</b>.</li>
|
|
<ol>
|
|
<li>If <b>Add C/C++ Watchpoint</b> is not listed on the Run menu, select <b>Window
|
|
> Customize Perspective</b>.</li><li>In the Customize Perspective dialog
|
|
box, expand <b>Other</b> in the <b>Available Items</b> list.</li><li>Select the <b>C/C++ Debug</b> check box. Click <b>OK</b>.</li>
|
|
</ol>
|
|
<li>In the <b>Add C/C++ Watchpoint</b> dialog box, type an expression in the <b>Expression to watch</b>
|
|
box. The
|
|
expression may be anything that can be evaluated inside an <samp>if</samp>
|
|
statement.</li>
|
|
<li>Do any of the following:</li>
|
|
<ul><li>To stop execution when the watch expression is read, select the
|
|
<b>Read</b> check box.</li>
|
|
<li>To stop execution when the watch expression is written to, select the <b>Write</b>
|
|
check box.</li></ul>
|
|
<li>In the C/C++ editor, open the file that you added the watchpoint to.</li>
|
|
<li>Click <b>OK</b>.</li>
|
|
<li>The watchpoint appears in the <b>Breakpoints</b> view
|
|
list.</li>
|
|
</ol>
