<h1>Working with memory</h1>
|
|
|
16 |
|
|
|
17 |
<p>You can inspect and change process memory.</p>
|
|
|
18 |
|
|
|
19 |
<p>The Memory view supports the same addressing as the C and C++ languages. You can address memory using expressions
|
|
|
20 |
such as:</p>
|
|
|
21 |
|
|
|
22 |
<ul>
|
|
|
23 |
<li><samp>0x0847d3c</samp></li>
|
|
|
24 |
<li><samp>(&y)+1024</samp></li>
|
|
|
25 |
<li><samp>*ptr</samp></li>
|
|
|
26 |
</ul>
|
|
|
27 |
|
|
|
28 |
<p> You can configure your output to
|
|
|
29 |
display hexadecimal, ascii and/or signed/unsigned decimal. You can also set the
|
|
|
30 |
size of the rendering columns. You can configure each memory monitor renderings
|
|
|
31 |
independently.</p>
|
|
|
32 |
|
|
|
33 |
<p> You can customize the Memory view to colors and fonts displayed. </p>
|
|
|
34 |
|
|
|
35 |
<p>To monitor process memory:</p>
|
|
|
36 |
<ol>
|
|
|
37 |
<li> In the Debug view, select a debug session. Selecting a thread or stack frame automatically
|
|
|
38 |
selects the associated session.</li>
|
|
|
39 |
|
|
|
40 |
<li> Select <strong>"Add Memory Monitor"</strong> in the context menu of the Memory Monitors pane.
|
|
|
41 |
The <strong>"Memory Monitor"</strong> dialog appears.</li>
|
|
|
42 |
|
|
|
43 |
<li> Type the address or expression that specifies the memory section you want to monitor and
|
|
|
44 |
press <strong>"OK"</strong>. The monitor appears in the monitor list and the Memory Renderings
|
|
|
45 |
pane displays the contents of memory locations beginning at the specified address.</li>
|
|
|
46 |
|
|
|
47 |
</ol>
|
|
|
48 |
<p>To view memory in a different rendering: </p>
|
|
|
49 |
<ol>
|
|
|
50 |
<li> Select <strong>"Add Rendering"</strong> in the context menu of the Memory Renderings pane.
|
|
|
51 |
The <strong>"Add Memory Rendering"</strong> dialog appears.</li>
|
|
|
52 |
|
|
|
53 |
<li> Select renderings from the list and press <strong>"OK"</strong>.</li>
|
|
|
54 |
</ol>
|
|
|
55 |
<p>To change process memory:</p>
|
|
|
56 |
|
|
|
57 |
<p><b>Warning:</b>
|
|
|
58 |
Changing process memory can cause a program to crash.</p>
