* @note We assume that your system has inttypes.h. If your system
|
||
|
* doesn't have inttypes.h, you have to typedef uint32_t and uint64_t,
|
||
|
* and you have to define PRIu64 and PRIx64 in this file as follows:
|
||
|
* @verbatim
|
||
|
typedef unsigned int uint32_t
|
||
|
typedef unsigned long long uint64_t
|
||
|
#define PRIu64 "llu"
|
||
|
#define PRIx64 "llx"
|
||
|
@endverbatim
|
||
|
* uint32_t must be exactly 32-bit unsigned integer type (no more, no
|
||
|
* less), and uint64_t must be exactly 64-bit unsigned integer type.
|
||
|
* PRIu64 and PRIx64 are used for printf function to print 64-bit
|
||
|
* unsigned int and 64-bit unsigned int in hexadecimal format.
