uint8_t、uint16_t、uint32_t、uint64_t、size_t、ssize_t、

我们经常创建C/C++项目中的程序是32位的控制台程序。所以，此处是针对32位的控制台程序（一般都是32位）：

typedef unsigned char uint8_t;typedef signed char int8_t;typedef unsigned short uint16_t;typedef signed short int16_t;typedef unsigned int uint32_t;typedef signed int int32_t;typedef unsigned long uint64_t;typedef signed long int64_t;typedef unsigned int size_t;typedef int ssize_t;

如果实在不想为了几个数据类型的名称引用整个头文件，那么就如上的代码进行定义计科。
