       The function SSL_CONF_cmd_argv() processes at most two command line arguments from pargv and pargc. The
       values of pargv and pargc are updated to reflect the number of command options processed. The pargc
       argument can be set to NULL if it is not used.

       These functions were added in OpenSSL 1.0.2.

       SSL_CONF_cmd_argv - SSL configuration command line processing

SSL_CONF_cmd_argv() returns the number of command arguments processed: 0, 1, 2 or a negative error code.

       If -2 is returned then an argument for a command is missing.

       If -1 is returned the command is recognised but couldn't be processed due to an error: for example a
       syntax error in the argument.
