.SH NAME
ECPKParameters_print, ECPKParameters_print_fp \- Functions for decoding and
encoding ASN1 representations of elliptic curve entities
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/ec.h>
.Ve
.PP
The following functions have been deprecated since OpenSSL 3.0, and can be
hidden entirely by defining \fBOPENSSL_API_COMPAT\fR with a suitable version value,
see \fBopenssl_user_macros\fR\|(7):
.PP
.Vb 2

.SH DESCRIPTION
.IX Header "DESCRIPTION"
All of the functions described on this page are deprecated.
Applications should instead use \fBEVP_PKEY_print_params\fR\|(3)
.PP
The ECPKParameters represent the public parameters for an
\&\fBEC_GROUP\fR structure, which represents a curve.
.PP
The \fBECPKParameters_print()\fR and \fBECPKParameters_print_fp()\fR functions print
a human-readable output of the public parameters of the EC_GROUP to \fBbp\fR
or \fBfp\fR. The output lines are indented by \fBoff\fR spaces.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBECPKParameters_print()\fR and \fBECPKParameters_print_fp()\fR
return 1 for success and 0 if an error occurs.
