<h2>Status Of A Dynamic String</h2>
</div>
<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.
