Depending on the command ccmmdd the arguments llaarrgg, ppaarrgg, or ffpp are evaluated. These functions should never be called directly. All functionalities needed are made available via other func- tions or macros. RREETTUURRNN VVAALLUUEESS The return values of the SSL*___c_t_r_l_(_) functions depend on the command supplied via the ccmmdd parameter. SSEEEE AALLSSOO _s_s_l(3) 1.0.2u 2019-12-20 SSL_CTX_ctrl(3)
