<h2 class="chapter">15 Using <span class="sc">gdb</span> with Different Languages</h2>

|

|
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>.
