std::va_list(3)		      C++ Standard Libary	       std::va_list(3)

NAME
       std::va_list - std::va_list

Synopsis
	  Defined in header <cstdarg>
	  typedef /* unspecified */ va_list;

	  va_list  is a	complete object	type suitable for holding the informa-
       tion needed by the
	  macros va_start, va_copy, va_arg, and	va_end.

	  If a va_list instance	is created, passed to  another	function,  and
       used via	va_arg in
	  that	function,  then	 any  subsequent  use  in the calling function
       should be preceded by
	  a call to va_end.

	  It is	legal to pass a	pointer	to a va_list object to	another	 func-
       tion and	then use
	  that object after the	function returns.
