<p>
<dt>
<b>Returns</b>

<b>Format string</b>
<p>
See <a href=255.htm>printf</a>.
<p>
<b>Binary zero characters</b>
<p>
Note that <tt>sprintf</tt> can not return strings with embedded binary zero
characters (0x00). If the resulting string contains a binary zero character,
any characters following that zero character will be dropped.
Use <a href=255.htm>printf</a> if you need to output binary data.

<pre>
string result;
int number = 42;
sprintf(result, "The number is %d", number);
