<h2>Add Content To A Dynamic String</h2>
</div>
<blockquote><pre>
void sqlite3_str_appendf(sqlite3_str*, const char *zFormat, ...);
void sqlite3_str_vappendf(sqlite3_str*, const char *zFormat, va_list);
void sqlite3_str_append(sqlite3_str*, const char *zIn, int N);

</pre></blockquote>
<p>
These interfaces add content to an sqlite3_str object previously obtained
from <a href="../c3ref/str_new.html">sqlite3_str_new()</a>.</p>
<p>The <a href="../c3ref/str_append.html">sqlite3_str_appendf(X,F,...)</a> and
<a href="../c3ref/str_append.html">sqlite3_str_vappendf(X,F,V)</a> interfaces uses the <a href="../printf.html">built-in printf</a>
functionality of SQLite to append formatted text onto the end of
<a href="../c3ref/str.html">sqlite3_str</a> object X.</p>
<p>The <a href="../c3ref/str_append.html">sqlite3_str_append(X,S,N)</a> method appends exactly N bytes from string S
onto the end of the <a href="../c3ref/str.html">sqlite3_str</a> object X. N must be non-negative.
S must contain at least N non-zero bytes of content. To append a
zero-terminated string in its entirety, use the <a href="../c3ref/str_append.html">sqlite3_str_appendall()</a>
method instead.</p>
<p>The <a href="../c3ref/str_append.html">sqlite3_str_appendall(X,S)</a> method appends the complete content of
zero-terminated string S onto the end of <a href="../c3ref/str.html">sqlite3_str</a> object X.</p>
<p>The <a href="../c3ref/str_append.html">sqlite3_str_appendchar(X,N,C)</a> method appends N copies of the
single-byte character C onto the end of <a href="../c3ref/str.html">sqlite3_str</a> object X.
This method can be used, for example, to add whitespace indentation.</p>
<p>The <a href="../c3ref/str_append.html">sqlite3_str_reset(X)</a> method resets the string under construction
inside <a href="../c3ref/str.html">sqlite3_str</a> object X back to zero bytes in length.</p>
<p>These methods do not return a result code. If an error occurs, that fact
is recorded in the <a href="../c3ref/str.html">sqlite3_str</a> object and can be recovered by a
subsequent call to <a href="../c3ref/str_errcode.html">sqlite3_str_errcode(X)</a>.

<a href="objlist.html">Objects</a>,
