<p>ECPKParameters_print, ECPKParameters_print_fp - Functions for decoding and encoding ASN1 representations of elliptic curve entities</p>

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

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

<p>The following functions have been deprecated since OpenSSL 3.0, and can be hidden entirely by defining <b>OPENSSL_API_COMPAT</b> with a suitable version value, see <a href="../man7/openssl_user_macros.html">openssl_user_macros(7)</a>:</p>

<pre><code>int ECPKParameters_print(BIO *bp, const EC_GROUP *x, int off);
int ECPKParameters_print_fp(FILE *fp, const EC_GROUP *x, int off);</code></pre>

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

<p>All of the functions described on this page are deprecated. Applications should instead use <a href="../man3/EVP_PKEY_print_params.html">EVP_PKEY_print_params(3)</a></p>

<p>The ECPKParameters represent the public parameters for an <b>EC_GROUP</b> structure, which represents a curve.</p>

<p>The ECPKParameters_print() and ECPKParameters_print_fp() functions print a human-readable output of the public parameters of the EC_GROUP to <b>bp</b> or <b>fp</b>. The output lines are indented by <b>off</b> spaces.</p>

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

<p>ECPKParameters_print() and ECPKParameters_print_fp() return 1 for success and 0 if an error occurs.</p>

<p>All of these functions were deprecated in OpenSSL 3.0.</p>
