pll->rate is of type uint64_t incompatible with "%llu"
Type uint64_t is included from /usr/include/stdint.h as
typedef unsigned long long int uint64_t;
From /usr/include/stdint.h ,the uint64_t is defined by:
#if __WORDSIZE == 64
typedef unsigned long int uint64_t;
#else
__extension__
typedef unsigned long long int uint64_t;
#endif
On my machine(64 bit), there will be a incompatibility error.
Yes, I have understood now. I don't use neither 64 bit system nor
compiler and have not ever faced with this problem. Thanks for remarks
As Peter said, you should use PRIu64 instead of llu
and 'll' specifies that a following 'u' conversion specifier applies to a
unsigned long long argument
Why do you think they incompatible?
