I need to obtain:
In fact, I get garbage output. What is definitely wrong in this program code?
with uprintf. So I went to IAR to try but no luck. Then i start looking in the libraries of GCC for 'uprintf.c' i found it and i try to recreate something similar for IAR. But uprintf.c is calling other routines that are not in IAR stdio lib. Does anyone have done something similar. Any give a hint will be appreciated. Hi Francisco!

Rather of printf, I suggest you try vprintf instead, which had been made for this particular purpose:

As others have got directed out already: In this situation you should use
vprintf
rather.But if you actually want to wrap
printf
, or need to cover a function that will not possess av.
edition, you can perform that in GCC using the non-standardbuiltinapply
feature:The final argument to
vaxquisbuiltinapply
will be the utmost. total size of the fights in bytes. Make sure that you make use of a worth here that is large enough.8,0605 yellow metal badges40 sterling silver badges58 bronze badges

This can be not really how you use

. If you would like to make use ofvalists
