基本类型在Poco/Types.h
头文件中。以下以 GNU C/C++ 和 CLang 为例。不过要强调的是,POCO 有极好的跨平台性,你能想到的平台,几乎都可以运行 POCO。
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
#define POCO_LONG_IS_64_BIT 1
typedef signed long Int64;
typedef unsigned long UInt64;
#else
typedef signed long long Int64;
typedef unsigned long long UInt64;
#endif
#define POCO_HAVE_INT64 1
