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.
