</a><h3>Ns_DStringNAppend</h3>
<a name="120617">
</a><h4>Overview</h4>
Append n-characters of a string to an Ns_DString
<a name="43833">
</a><a name="132902">
</a><h4>Syntax</h4>
<pre> <a name="43834"></a>char *Ns_DStringNAppend(
<a name="43835"></a>Ns_DString *dsPtr,
<a name="43836"></a>char *string,
<a name="43837"></a>int length
<a name="43838"></a>);
</pre><p><a name="134240">
</a><h4>Description</h4>
<p><a name="43840">
</a>The Ns_DStringNAppend function appends a string up to the specified number of characters, plus a terminating null character.( Unlike the Tcl_DStringAppend function, which only works with string data, the AOLserver Ns_DStringNAppend function can append binary data.) The string may overflow from static space to the heap as a result of calling this function. It returns the string associated with the current Ns_DString.</p>
<a name="230689">
</a><h4>Examples</h4>
<p><a name="435436">
</a>The resulting Ns_DString in this example, <code>ds</code>, would contain "foo\0" and have a length of 3:</p>
<pre> <a name="230690"></a>Ns_DString ds;
<a name="230691"></a>Ns_DStringInit(&ds);
<a name="230692"></a>Ns_DStringNAppend(&ds, "fooasdf", 3);
<a name="230694"></a>printf("%s\n", ds.string);
<a name="230701"></a>Ns_DStringFree(&ds); /* finished with dstring */
</pre><p><p><a name="435424">
</a>If you need a null-terminated list of null-terminated strings, such as "foo\0bar\0\0", you would add one to the length of the appended strings to get the extra terminating null character. For example:</p>
<pre> <a name="435431"></a>Ns_DString ds;
<a name="435432"></a>Ns_DStringInit(&ds);
<a name="435433"></a>Ns_DStringNAppend(&ds, "foo", 4);
<a name="435443"></a>Ns_DStringNAppend(&ds, "bar", 4);
