specifying global variables and functions.
|

|

<p>For example, given the program:
|

|
|
|

|
<pre class="example"> package main

var myglob = "Shall we?"

// ...

</pre>
|

|
|
<p>When stopped inside <code>main</code> either of these work:
|
||
|
|
|
||
|
|
<pre class="example"> (gdb) p myglob

(gdb) p main.myglob

<p><a name="index-builtin-Go-functions-1017"></a><br><dt><code>Builtin Go functions</code><dd>The <span class="sc">gdb</span> expression parser recognizes the <code>unsafe.Sizeof</code>

<p><a name="index-restrictions-on-Go-expressions-1018"></a><br><dt><code>Restrictions on Go expressions</code><dd>All Go operators are supported except <code>&^</code>.
