+<blockquote><pre>
+int sqlite3_str_errcode(sqlite3_str*);
+int sqlite3_str_length(sqlite3_str*);
+char *sqlite3_str_value(sqlite3_str*);
+</pre></blockquote>
+<p>
+These interfaces return the current status of an <a href="../c3ref/str.html">sqlite3_str</a> object.</p>
+
+<p>If any prior errors have occurred while constructing the dynamic string
+in sqlite3_str X, then the <a href="../c3ref/str_errcode.html">sqlite3_str_errcode(X)</a> method will return
+an appropriate error code.  The <a href="../c3ref/str_errcode.html">sqlite3_str_errcode(X)</a> method returns
+<a href="../rescode.html#nomem">SQLITE_NOMEM</a> following any out-of-memory error, or
+<a href="../rescode.html#toobig">SQLITE_TOOBIG</a> if the size of the dynamic string exceeds
+<a href="../limits.html#max_length">SQLITE_MAX_LENGTH</a>, or <a href="../rescode.html#ok">SQLITE_OK</a> if there have been no errors.</p>
+
+<p>The <a href="../c3ref/str_errcode.html">sqlite3_str_length(X)</a> method returns the current length, in bytes,
+of the dynamic string under construction in <a href="../c3ref/str.html">sqlite3_str</a> object X.
+The length returned by <a href="../c3ref/str_errcode.html">sqlite3_str_length(X)</a> does not include the
+zero-termination byte.</p>
+
+<p>The <a href="../c3ref/str_errcode.html">sqlite3_str_value(X)</a> method returns a pointer to the current
+content of the dynamic string under construction in X.  The value
+returned by <a href="../c3ref/str_errcode.html">sqlite3_str_value(X)</a> is managed by the sqlite3_str object X
+and might be freed or altered by any subsequent method on the same
+<a href="../c3ref/str.html">sqlite3_str</a> object.  Applications must not used the pointer returned
+<a href="../c3ref/str_errcode.html">sqlite3_str_value(X)</a> after any subsequent method call on the same
+object.  Applications may change the content of the string returned
+by <a href="../c3ref/str_errcode.html">sqlite3_str_value(X)</a> as long as they do not write into any bytes
+outside the range of 0 to <a href="../c3ref/str_errcode.html">sqlite3_str_length(X)</a> and do not read or
+write any byte after any subsequent sqlite3_str method call.
