Syntax:
</p>
<pre class="c code c++" style="font-family:monospace;"> <span class="co2">#include <cstring></span>
<span class="kw4">int</span> strncmp<span class="br0">(</span> <span class="kw4">const</span> <span class="kw4">char</span> <span class="sy0">*</span>str1<span class="sy0">,</span> <span class="kw4">const</span> <span class="kw4">char</span> <span class="sy0">*</span>str2<span class="sy0">,</span> size_t count <span class="br0">)</span><span class="sy0">;</span></pre>
<p>
The strncmp() function compares at most count characters of str1 and str2. The
return value is as follows:
</p>
<table class="inline">
<tr class="row0">
<th class="col0 leftalign">Return value </th><th class="col1">Explanation</th>
</tr>
<tr class="row1">
<td class="col0 leftalign">less than 0 </td><td class="col1"><code>str1</code> is less than <code>str2</code></td>
</tr>
<tr class="row2">
<td class="col0 leftalign">equal to 0 </td><td class="col1"><code>str1</code> is equal to <code>str2</code></td>
</tr>
<tr class="row3">
<td class="col0">greater than 0 </td><td class="col1"><code>str1</code> is greater than <code>str2</code></td>
</tr>
</table>
<p>
If there are less than count characters in either string, then the comparison
will stop after the first null termination is encountered.
