Does va_return_type automatically returns?

[Name Surname]

Does va_return_type automatically returns or do I have to add a return 
statement?

    void func(...) {
        va_start ...

        if (cond)
            va_return ...
    }


or this?

    void func(...) {
        va_start ...

        if (cond) {
            va_return ...
            return;
        }
    }
