157 \&\fISSL_get_ciphers()\fR returns the stack of available SSL_CIPHERs for \fBssl\fR,
158 sorted by preference. If \fBssl\fR is \s-1NULL\s0 or no ciphers are available, \s-1NULL\s0
159 is returned.

161 \&\fISSL_get_cipher_list()\fR returns a pointer to the name of the \s-1SSL_CIPHER\s0
162 listed for \fBssl\fR with \fBpriority\fR. If \fBssl\fR is \s-1NULL,\s0 no ciphers are
163 available, or there are less ciphers than \fBpriority\fR available, \s-1NULL\s0
164 is returned.
