Question

Having the signature of the function :

int my_print(const char *format, ...);

I want to implement it by calling printf with arguments passed to my_print and fflush(stdout);

What do you think the best way to implement it?

Answer 1

You can use vprintf. It accepts a va_list, which is what you get in my_print:

int my_print(char * format, ...)
{
  va_list args;
  va_start (args, format);
  int ret = vprintf (format, args);
  va_end (args);
  return ret;
}
