Hello folks

I'm trying to write a func format(), which should replace sprintf(), using va_list etc. At my machine it runs, but it's printing only trash. Could someone have a look please.

Here ist the code:

The second func sum() there is running fine.

Maybe that's why I'm using sprintf() also? That means, two va_lists are running at the same time boxed. Could that do a harm maybe?

Hello Amando

A lot easier. Just replace "count" with "f" in va_start(li, count);

Nothing else Smile

Best regards

Hi Koldo

Good idea. Now it's printing all the args, only the first one is missing, %i (which is 4), though I get the report:

typefound = 'i'.

alike for the other three args. The output at my machine is now:

==>  args wrapped, double == 0.456124f

Thanks for the hint.
