<p>This function is similar to <a class="reference internal" href="krb5_unparse_name.html#krb5_unparse_name" title="krb5_unparse_name"><tt class="xref c c-func docutils literal"><span class="pre">krb5_unparse_name()</span></tt></a> , but allows the use of an existing buffer for the result. If size is not NULL, then <em>name</em> must point to either NULL or an existing buffer of at least the size pointed to by <em>size</em> . The buffer will be allocated or resized if necessary, with the new pointer stored into <em>name</em> . Whether or not the buffer is resized, the necessary space for the result, including null terminator, will be stored into <em>size</em> .</p>
<p>If size is NULL, this function behaves exactly as <a class="reference internal" href="krb5_unparse_name.html#krb5_unparse_name" title="krb5_unparse_name"><tt class="xref c c-func docutils literal"><span class="pre">krb5_unparse_name()</span></tt></a> .</p>
