<h3 class="section">5.1 Builtin Types</h3>
|
|
<p>Certain types are built in (<code>int</code>, <code>short</code>, <code>void</code>,
|
<code>float</code>, etc.); the debugger recognizes these types and knows how
|
to handle them. Thus, don’t be surprised if some of the following ways
|
of specifying builtin types do not specify everything that a debugger
|
would need to know about the type—in some cases they merely specify
|
enough information to distinguish the type from other types.
|
</p>
|
<p>The traditional way to define builtin types is convoluted, so new ways
|
have been invented to describe them. Sun’s <code>acc</code> uses special
|
builtin type descriptors (‘<samp>b</samp>’ and ‘<samp>R</samp>’), and IBM uses negative
|
type numbers. GDB accepts all three ways, as of version 4.8; dbx just
|
accepts the traditional builtin types and perhaps one of the other two
|
formats. The following sections describe each of these formats.
