std::va_list
Defined in header <cstdarg> | ||
|---|---|---|
typedef /* unspecified */ va_list; |
va_list is a complete object type (in practice, a unique built-in type or char*) 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.
