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 information 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 function and then use
that object after the function returns.
