 macro to obtain the number of secret/algorithm bits used and
 SSL_get_cipher_version() returns the protocol name.
 
+SSL_get_pending_cipher() returns a pointer to an SSL_CIPHER object containing
+the description of the cipher (if any) that has been negotiated for future use
+on the connection established with the B<ssl> object, but is not yet in use.
+This may be the case during handshake processing, when control flow can be
+returned to the application via any of several callback methods.  The internal
+sequencing of handshake processing and callback invocation is not guaranteed
+to be stable from release to release, and at present only the callback set
+by SSL_CTX_set_alpn_select_cb() is guaranteed to have a non-NULL return value.
+Other callbacks may be added to this list over time.
+
 =head1 RETURN VALUES
 
 SSL_get_current_cipher() returns the cipher actually used, or NULL if
 no session has been established.
 
+SSL_get_pending_cipher() returns the cipher to be used at the next change
+of cipher suite, or NULL if no such cipher is known.
