used to iterate over all certificates in an B<SSL_CTX> structure.



SSL_set_current_cert() also supports the option B<SSL_CERT_SET_SERVER>.

If B<ssl> is a server and has sent a certificate to a connected client

this option sets that certificate to the current certificate and returns 1.

If the negotiated ciphersuite is anonymous (and thus no certificate will

be sent) 2 is returned and the current certificate is unchanged. If B<ssl>

is not a server or a certificate has not been sent 0 is returned and

the current certificate is unchanged.



All these functions are implemented as macros. Those containing a B<1>

increment the reference count of the supplied certificate or chain so it must

be freed at some point after the operation. Those containing a B<0> do
