Sprintf32 Bug?

[Neil 0]

Hi All

 

I think this shows a lib / compiler bug. If you run this code in the debuger (and on a real PIC18F) then the 32 bit function produces an error.

 

sprintf32 gives 999

sprintf gives 9999

 

So, sprintf32 misses out one digit. It only seems to do this for numbers over 99. I have not looked at negative numbers

 

Can this be confirmed as a bug? If so can it be fixed?

 

Thanks

 

Neil

 

OS XPpro, BoostC++ 6.90 PIC18f8722

 

 

	char buf[64];
char* bufP = buf;

unsigned long tl = 9999;
sprintf32(bufP, "%d", tl);

unsigned int ti = 9999;
sprintf(bufP, "%d", ti);

 

I know I dot need bufP but this helps the debugger show the text string in the watch window.

 

 

I have now compiled the sprintf32 code in libc and this works just fine for me.

This is the only reference to sprintf32 I can find.

When I try and compile using this command I get this error:

 

error: unknown identifier 'sprintf32'

What am I missing here??

 

Thanks,

Robert

Hi Robert,

 

The manual says it is included in stdio.h. Have you included this header file into your code ?

 

Cheers

Thanks.

That helped me realize I loaded an old version that didn't have that function yet.
