Depending on the command B<cmd> the arguments 21B<larg>, B<parg>, or B<fp> are evaluated. These functions should never 22be called directly. All functionalities needed are made available via 23other functions or macros. 24 25=head1 RETURN VALUES 26 27The return values of the SSL*_ctrl() functions depend on the command 28supplied via the B<cmd> parameter. 29 30=head1 SEE ALSO 31 32L<ssl(3)|ssl(3)> 33 34=cut 35
