<p>CRYPTO_memcmp - Constant time memory comparison</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code> #include &lt;openssl/crypto.h&gt;

 int CRYPTO_memcmp(const void *a, const void *b, size_t len);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>The CRYPTO_memcmp function compares the <b>len</b> bytes pointed to by <b>a</b> and <b>b</b> for equality. It takes an amount of time dependent on <b>len</b>, but independent of the contents of the memory regions pointed to by <b>a</b> and <b>b</b>.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>CRYPTO_memcmp() returns 0 if the memory regions are equal and nonzero otherwise.</p>

<h1 id="NOTES">NOTES</h1>

<p>Unlike memcmp(2), this function cannot be used to order the two memory regions as the return value when they differ is undefined, other than being nonzero.</p>
