=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_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)>, 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).
