5ECPKParameters_print, ECPKParameters_print_fp - Functions for decoding and
6encoding ASN1 representations of elliptic curve entities
7
8=head1 SYNOPSIS
9
10 #include <openssl/ec.h>
11
12The following functions have been deprecated since OpenSSL 3.0, and can be
13hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
14see L<openssl_user_macros(7)>:
15
16 int ECPKParameters_print(BIO *bp, const EC_GROUP *x, int off);
17 int ECPKParameters_print_fp(FILE *fp, const EC_GROUP *x, int off);
18
19=head1 DESCRIPTION
20
21All of the functions described on this page are deprecated.
22Applications should instead use L<EVP_PKEY_print_params(3)>
23
24The ECPKParameters represent the public parameters for an
25B<EC_GROUP> structure, which represents a curve.
26
27The ECPKParameters_print() and ECPKParameters_print_fp() functions print
28a human-readable output of the public parameters of the EC_GROUP to B<bp>
29or B<fp>. The output lines are indented by B<off> spaces.
30
31=head1 RETURN VALUES
32
33ECPKParameters_print() and ECPKParameters_print_fp()
34return 1 for success and 0 if an error occurs.
