C++ POCO库中文编程参考指南(2) 基本数据类型(Poco/Types.h)2013-01-10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 Handlertypedef 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 longInt64; typedef unsigned longUInt64; #else typedef signed long long Int64; typedef unsigned long long UInt64; #endif #define POCO_HAVE_INT64 1
