Poco/Types.h

1 有符号整型

typedef signed char            Int8;

typedef signed short           Int16;

typedef signed int             Int32;

2 无符号整型

typedef unsigned char          UInt8;

typedef unsigned short         UInt16;

typedef unsigned int           UInt32;

3 Pointer or Handler

typedef signed long            IntPtr;

typedef unsigned long          UIntPtr;

4 64 位整型

考虑了 32 位机和 64 位机的情况

#if defined(LP64)


#define POCO_PTR_IS_64_BIT 1<br/>
#define POCO_LONG_IS_64_BIT 1<br/>
typedef signed long        Int64;<br/>
typedef unsigned long      UInt64;<br/>


#else


typedef signed long long   Int64;<br/>
typedef unsigned long long UInt64;<br/>


#endif

#define POCO_HAVE_INT64 1
