                     14: vvaa_ssttaarrtt is  a macro that  points to the  beginning of a  list of
                     15: arguments.  It  can be used  with functions that  take a variable
                     16: number of  arguments, such as pprriinnttff or  ssccaannff, to help implement
                     17: them portably.   It is  always used  with vvaa_aarrgg and  vvaa_eenndd from
                     18: within a function that takes a variable number of arguments.

                     20: _l_i_s_t_p_t_r is of type vvaa_lliisstt, which is a type defined in the header

                     24: parameter list.   Its type is  set by the function  that is using
                     25: vvaa_ssttaarrtt.  Undefined behavior  results  if any  of the  following

                     27: if it has a function type or an array type; or if its type is not
                     28: compatible with  the type that results  from the default argument

                     41: 
                     42: The ANSI Standard demands  that vvaa_ssttaarrtt be implemented only as a
                     43: macro.  If the  macro definition of vvaa_ssttaarrtt is suppressed within
                     44: a program, the behavior is undefined.
