| <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>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><span class="samp">b</span></samp>’ and ‘<samp><span class="samp">R</span></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. |
