|  |  | 
|  | SSL_CTX_add_extra_chain_cert - add certificate to chain | 
|  |  | 
|  | =head1 SYNOPSIS | 
|  |  | 
|  | #include <openssl/ssl.h> | 
|  |  | 
|  | long SSL_CTX_add_extra_chain_cert(SSL_CTX ctx, X509 *x509) | 
|  |  | 
|  | =head1 DESCRIPTION | 
|  |  | 
|  | SSL_CTX_add_extra_chain_cert() adds the certificate B<x509> to the certificate | 
|  | chain presented together with the certificate. Several certificates | 
|  | can be added one after the other. | 
|  |  | 
|  | =head1 NOTES | 
|  |  | 
|  | When constructing the certificate chain, the chain will be formed from | 
|  | these certificates explicitly specified. If no chain is specified, | 
|  | the library will try to complete the chain from the available CA | 
|  | certificates in the trusted CA storage, see | 
|  | L<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)>. | 
|  |  | 
|  | =head1 RETURN VALUES | 
|  |  | 
|  | SSL_CTX_add_extra_chain_cert() returns 1 on success. Check out the | 
|  | error stack to find out the reason for failure otherwise. |
