<a name="129874">
</a><h4>Overview</h4>
Locate the index of a field within an Ns_Set
<a name="41016">
</a><a name="133308">
</a><h4>Syntax</h4>
<pre> <a name="41018"></a>int Ns_SetFind(
<a name="41019"></a>Ns_Set *set,
<a name="41020"></a>char *key
<a name="41021"></a>);
</pre><p><a name="134730">
</a><h4>Description</h4>
<p><a name="41023">
</a>The Ns_SetFind function returns the index of the first field whose key name matches the given <code>key</code>. The index is in C array order, i.e., 0 is the index of the first field. If no fields are found, Ns_SetFind returns -1. If more than one field in the set has the same key name, Ns_SetFind returns just the first field index.</p>
<p><a name="41024">
</a>The Ns_SetIFind function is this function's case-insensitive counterpart.</p>
