NAME

       SSL_get_client_CA_list, SSL_CTX_get_client_CA_list - get list of client CAs

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);

DESCRIPTION

       SSL_CTX_get_client_CA_list() returns the list of client CAs explicitly set for ctx using
       SSL_CTX_set_client_CA_list(3).

       SSL_get_client_CA_list() returns the list of client CAs explicitly set for ssl using
       SSL_set_client_CA_list() or ssl's SSL_CTX object with 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.

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:

       STACK_OF(X509_NAMES)
           List of CA names explicitly set (for ctx or in server mode) or send by the server
           (client mode).

       NULL
           No client CA list was explicitly set (for ctx or in server mode) or the server did not
           send a list of CAs (client mode).
