c++ 哪些自定义的数据类型

http://www.cnblogs.com/ShaneZhang/archive/2013/06/21/3147648.html

这些数据类型是 C99 中定义的，具体定义在：/usr/include/stdint.h    ISO C99: 7.18 Integer types <stdint.h>

 1 /* There is some amount of overlap with <sys/types.h> as known by inet code */  2 #ifndef __int8_t_defined  3 # define __int8_t_defined  4 typedef signed char int8_t;  5 typedef short int int16_t;  6 typedef int int32_t;  7 # if __WORDSIZE == 64  8 typedef long int int64_t;  9 # else 10 __extension__ 11 typedef long long int int64_t; 12 # endif 13 #endif 14 15 /* Unsigned. */ 16 typedef unsigned char uint8_t; 17 typedef unsigned short int uint16_t; 18 #ifndef __uint32_t_defined 19 typedef unsigned int uint32_t; 20 # define __uint32_t_defined 21 #endif 22 #if __WORDSIZE == 64 23 typedef unsigned long int uint64_t; 24 #else 25 __extension__ 26 typedef unsigned long long int uint64_t; 27 #endif

格式化输出：

unit64_t     %llu   

unit32_t     %u

unit16_t    %hu
