=head1 NAME
SSL_get_client_CA_list, SSL_CTX_get_client_CA_list - get list of client CAs
=head1 SYNOPSIS
#include <openssl/ssl.h>
STACK_OF(X509_NAME) *SSL_get_client_CA_list(const SSL *s);
STACK_OF(X509_NAME) *SSL_CTX_get_client_CA_list(const SSL_CTX *ctx);
=head1 DESCRIPTION
SSL_CTX_get_client_CA_list() returns the list of client CAs explicitly set for
B<ctx> using L<SSL_CTX_set_client_CA_list(3)|SSL_CTX_set_client_CA_list(3)>.
SSL_get_client_CA_list() returns the list of client CAs explicitly
set for B<ssl> using SSL_set_client_CA_list() or B<ssl>'s SSL_CTX object with
L<SSL_CTX_set_client_CA_list(3)|SSL_CTX_set_client_CA_list(3)>, when in
server mode. In client mode, SSL_get_client_CA_list returns the list of
client CAs sent from the server, if any.
=head1 RETURN VALUES
SSL_CTX_set_client_CA_list() and SSL_set_client_CA_list() do not return
diagnostic information.
SSL_CTX_add_client_CA() and SSL_add_client_CA() have the following return
values:
=over 4
=item STACK_OF(X509_NAMES)
List of CA names explicitly set (for B<ctx> or in server mode) or send
by the server (client mode).
=item NULL
No client CA list was explicitly set (for B<ctx> or in server mode) or
the server did not send a list of CAs (client mode).
