=head1 NAME

ECPKParameters_print, ECPKParameters_print_fp - Functions for decoding and
encoding ASN1 representations of elliptic curve entities

=head1 SYNOPSIS

 #include <openssl/ec.h>

The following functions have been deprecated since OpenSSL 3.0, and can be
hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
see L<openssl_user_macros(7)>:

 int ECPKParameters_print(BIO *bp, const EC_GROUP *x, int off);
 int ECPKParameters_print_fp(FILE *fp, const EC_GROUP *x, int off);

=head1 DESCRIPTION

All of the functions described on this page are deprecated.
Applications should instead use L<EVP_PKEY_print_params(3)>

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

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

=head1 RETURN VALUES

ECPKParameters_print() and ECPKParameters_print_fp()
return 1 for success and 0 if an error occurs.

L<EC_GFp_simple_method(3)>,

=head1 HISTORY

All of these functions were deprecated in OpenSSL 3.0.
