C++ Passing va_list to a function

Question:

Tell me how to implement the function:

int test(...){ printf(...);}

That is, pass the va_list parameters to the next function.

Answer:

It's impossible to pass an undefined list of arguments just like that, there is no syntax for this in the language. However, the problem can be worked around, as noted here : the function you pass control to must have a variant that accepts va_list .

For your case, you can use vprintf :

void test(char *format, ...) // должен быть хотя бы один аргумент
{
    va_list args;
    va_start(args, format);
    vprintf(format, args);
    va_end(args);
}
