|
|
|
|
<p>Here is how a C<tt>++</tt> <code>std::string</code> looks without a pretty-printer:
|
|
</p>
|
|
<div class="smallexample">
|
|
<pre class="smallexample">(gdb) print s
|
|
$1 = {
|
|
static npos = 4294967295,
|
|
_M_dataplus = {
|
|
<std::allocator<char>> = {
|
|
<__gnu_cxx::new_allocator<char>> = {
|
|
<No data fields>}, <No data fields>
|
|
},
|
|
members of std::basic_string<char, std::char_traits<char>,
|
|
std::allocator<char> >::_Alloc_hider:
|
|
_M_p = 0x804a014 "abcd"
|
|
}
|
|
}
|
|
</pre></div>
|
|
|
|
<p>With a pretty-printer for <code>std::string</code> only the contents are printed:
|
|
</p>
|
|
<div class="smallexample">
|
|
<pre class="smallexample">(gdb) print s
|
|
$2 = "abcd"
|
|
</pre></div>
|
|
|
|
|
|
|
|
|
|
</body>

</html>
