Maybe your compiler doesn't understand the %llu syntax. If it's a
posix-compatible compiler, try this (although if it was posix, %llu
would have worked, so this probably won't either):
#include <inttypes.h>
...
sprintf(s,"%"PRIu64"\n",ull.id);
Or read your compiler documentation to verify that can print 64-bit
integers at all.
