Depending on the command B<cmd> the arguments 21*4724848cSchristosB<larg>, B<parg>, or B<fp> are evaluated. These functions should never 22*4724848cSchristosbe called directly. All functionalities needed are made available via 23*4724848cSchristosother functions or macros. 24*4724848cSchristos 25*4724848cSchristos=head1 RETURN VALUES 26*4724848cSchristos 27*4724848cSchristosThe return values of the SSL*_ctrl() functions depend on the command 28*4724848cSchristossupplied via the B<cmd> parameter. 29*4724848cSchristos 30*4724848cSchristos=head1 SEE ALSO 31*4724848cSchristos 32*4724848cSchristosL<ssl(7)> 33*4724848cSchristos 34*4724848cSchristos=head1 COPYRIGHT 35*4724848cSchristos 36*4724848cSchristosCopyright 2001-2016 The OpenSSL Project Authors.
