<p><code>std::strstreambuf</code> is a <span class="t-lc">std::basic_streambuf</span> whose associated character sequence is a character array, which may be constant (e.g. a string literal), modifyable but not dynamic (e.g. a stack-allocated array), or dynamic, in which case the <code>std::strstreambuf</code> may be allowed to reallocate the array as necessary to accomodate output (e.g. by calling <span class="t-c"><span class="mw-geshi cpp source-cpp">delete<span class="br0">[</span><span class="br0">]</span></span></span> and <span class="t-c"><span class="mw-geshi cpp source-cpp">new<span class="br0">[</span><span class="br0">]</span></span></span> or user-provided functions).
</p><p>Typical implementation of a <code>std::strstreambuf</code> holds four private data members:
</p>
<div class="t-li1"><span class="t-li">1)</span> buffer state, a bitmask type which can represent any combination of the four values "allocated" (destructor will deallocate), "constant" (output not allowed), "dynamic" (output may reallocate), or "frozen" (deallocation and reallocation are not allowed)</div>
<div class="t-li1"><span class="t-li">2)</span> allocated buffer size (the beginning of the buffer does not need a special data member, it may be stored in the inherited pointer <span class="t-lc">eback()</span>)</div>
