ios - osx上的 ‘I Space’和 ‘D Space’是什么以及它们之间的区别
<p><p>在 sys/ptrace.h 中，我看到了类似的内容:</p>
<pre><code>@define PT_READ_I1 /* read world in child's I space*/
@define PT_READ_D2 /* read world in child's D space*/
@define PT_READ_U3 /* read world in child's user structure*/
</code></pre>
<p>什么是“I Space”和“D Space”以及“用户结构”？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>引用手册页:</p>
<blockquote>
<p>Traditionally, ptrace() has
allowed for machines with distinct address spaces for
instruction and data, which is why there are two requests:
conceptually, PT_READ_I reads from the <strong>instruction space</strong>
and PT_READ_D reads from the <strong>data space</strong>.In the current
NetBSD implementation, these two requests are <strong>completely
identical.</strong></p>
</blockquote>
<p>现在关于 PT_READ_U:</p>
<blockquote>
<p>This space contains the registers andotherinformationaboutthe
process; its layout corresponds to the <strong>user structure</strong> in the system.</p>
</blockquote></p>
