On may 32-bit machine  -gcc version 3.3.2-
the following code 

#include <stdio.h>
int main()
{
	unsigned long long int x = 0x1000000000000001ULL;
	printf("size = %d , value = %llx  \n ",sizeof(x),x);
	return 1;
}

results in :
size = 8 , value = 1000000000000001

For me:
size = 8 , value = 1

gcc version 3.2.3 (mingw special 20030504-1)

Is that a MinGW bug or a gcc bug ?

Thanks aimen, m.

Took a look on the MinGW users mailing list archive and found that the 
MSVC runtime's printf() doesn't know about 'll'.
The solution is to use 'I64' instead of 'll'.

long long conversion specifier

[Sisyphus]

Hi,

On a 32 bit PC (Win32) what is the printf conversion specifier that I 
need to use in order to print out an unsigned 64 bit (long long) value ?

I can't believe the trouble I'm having in finding an answer ... I've 
found such things as 'llu', 'Lu', and 'l64u', but none of those work 
(either with or without a preceding '%') with my gcc (MinGW) compiler.

Also it would be really great if anyone can supply a weblink to a 
*complete* list of conversion specifiers.

Cheers,
Rob
