|
---|
| 18 | * and you have to define PRIu64 and PRIx64 in this file as follows:
|
---|
| 19 | * @verbatim
|
---|
| 20 | typedef unsigned int uint32_t
|
---|
| 21 | typedef unsigned long long uint64_t
|

| 23 | #define PRIx64 "llx"
|
---|
| 24 | @endverbatim
|
---|
| 25 | * uint32_t must be exactly 32-bit unsigned integer type (no more, no
|
---|
| 26 | * less), and uint64_t must be exactly 64-bit unsigned integer type.
|
---|
| 27 | * PRIu64 and PRIx64 are used for printf function to print 64-bit
|
---|
| 28 | * unsigned int and 64-bit unsigned int in hexadecimal format.
