std::va_list(3)

✨ NAME ✨

std::va_list - std::va_list — bestie, welcome to std::va_list(3), a page straight from the C++ Standard Libary, and it is literally about std::va_list 💅

💖 Synopsis 💖

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. That part is important, okay? 🫶

It is legal to pass a pointer to a va_list object to another function and then use that object after the function returns. No cap, that's the rule 🌸
