While the name suggests 22the specific usage as support function for 23L<SSL_CTX_set_client_CA_list(3)|SSL_CTX_set_client_CA_list(3)>, 24it is not limited to CA certificates. 25 26=head1 EXAMPLES 27 28Load names of CAs from file and use it as a client CA list: 29 30 SSL_CTX *ctx; 31 STACK_OF(X509_NAME) *cert_names; 32 33 ... 34 cert_names = SSL_load_client_CA_file("/path/to/CAfile.pem"); 35 if (cert_names != NULL) 36 SSL_CTX_set_client_CA_list(ctx, cert_names); 37 else 38 error_handling(); 39 ... 40 41=head1 RETURN VALUES 42 43The following return values can occur: 44 45=over 4 46 47=item NULL 48 49The operation failed, check out the error stack for the reason. 50 51=item Pointer to STACK_OF(X509_NAME) 52 53Pointer to the subject names of the successfully read certificates. 54 55=back 56 57=head1 SEE ALSO 58 59L<ssl(3)|ssl(3)>, 60L<SSL_CTX_set_client_CA_list(3)|SSL_CTX_set_client_CA_list(3)> 61 62=cut 63
