roar_vs_ctl - Interface to private internals of VS object

       This  function  is  used  to access internals of the VS object. It is generally to be avoided to use this
       function.  Valid commands depend on library version. Commands are defined in a way  suitable  for  #ifdef
       checking.

vss    The VS object to be altered.

       cmd    Specifies the command to use on object.

       argp   A pointer to the operant for the given command. Type depends on command. Must be NULL for commands
              not taking any argument.

       error  This  is  a pointer to a integer used to store the error value in case of error.  This can be NULL
              if not used but it is very recommended to use this error value to report good  error  messages  to
              the user.

       On success these calls return 0.  On error, -1 is returned.
