</a><h4>Overview</h4>
Return the current value of an Ns_DString
<a name="562460">
</a><a name="562461">
</a><h4>Syntax</h4>
<pre> <a name="562462"></a>char *Ns_DStringValue(

</a><h4>Description</h4>
<p><a name="562466">
</a>The Ns_DStringValue macro returns a pointer to the current value of an Ns_DString. This may be a pointer to the Ns_DString's static space or to a string allocated on the heap if the static space has overflowed. It is <i>not</i> safe to use the value returned by this macro after an intervening call to Ns_DStringAppend because the Ns_DString string could overflow to or move within the heap.</p>
<a name="562467">
</a><h4>Examples</h4>
<pre> <a name="562468"></a>Ns_DString ds;
<a name="562469"></a>Ns_DStringInit(&ds);
<a name="562470"></a>Ns_DStringAppend(&ds, "foo");
<a name="562471"></a>/* do something with the dstring */
<a name="562472"></a>printf ("%s\n", Ns_DStringValue(&ds));
<a name="562473"></a>Ns_DStringFree(&ds); /* finished with dstring */
