重新定义一些类型注意

重新定义一些类型，防止由于各种平台和编译器的不同，而产生的类型字节数差异，方便移植。

复制

1typedef unsigned char boolean; /* Boolean value type. */

2typedef unsigned long int uint32; /* Unsigned 32 bit value */

3typedef unsigned short uint16; /* Unsigned 16 bit value */

4typedef unsigned char uint8; /* Unsigned 8 bit value */

5typedef signed long int int32; /* Signed 32 bit value */

6typedef signed short int16; /* Signed 16 bit value */

7typedef signed char int8; /* Signed 8 bit value */

不建议使用：

复制

 1typedef unsigned char byte; /* Unsigned 8 bit value type. */

 2typedef unsigned short word; /* Unsinged 16 bit value type. */

 3typedef unsigned long dword; /* Unsigned 32 bit value type. */

 4typedef unsigned char uint1; /* Unsigned 8 bit value type. */

 5typedef unsigned short uint2; /* Unsigned 16 bit value type. */

 6typedef unsigned long uint4; /* Unsigned 32 bit value type. */

 7typedef signed char int1; /* Signed 8 bit value type. */

 8typedef signed short int2; /* Signed 16 bit value type. */

 9typedef long int int4; /* Signed 32 bit value type. */

10typedef signed long sint31; /* Signed 32 bit value */

11typedef signed short sint15; /* Signed 16 bit value */

12typedef signed char sint7; /* Signed 8 bit value */

unsigned char定义为byte有什么不妥吗？
