| <h2 class="chapter">15 Using <span class="sc">gdb</span> with Different Languages</h2> |
| |
| <p><a name="index-languages-965"></a> |
| Although programming languages generally have common aspects, they are |
| rarely expressed in the same manner. For instance, in ANSI C, |
| dereferencing a pointer <code>p</code> is accomplished by <code>*p</code>, but in |
| Modula-2, it is accomplished by <code>p^</code>. Values can also be |
| represented (and displayed) differently. Hex numbers in C appear as |
| ‘<samp><span class="samp">0x1ae</span></samp>’, while in Modula-2 they appear as ‘<samp><span class="samp">1AEH</span></samp>’. |
| |
| <p><a name="index-working-language-966"></a>Language-specific information is built into <span class="sc">gdb</span> for some languages, |
| allowing you to express operations like the above in your program's |
| native language, and allowing <span class="sc">gdb</span> to output values in a manner |
| consistent with the syntax of your program's native language. The |
| language you use to build expressions is called the <dfn>working |
| language</dfn>. |
