The LARGE_INTEGER structure is used to represent a 64-bit signed integer value. typedef struct _LARGE_INTEGER {
The low-order32bits. HighPart The high-order32bits. QuadPart A signed64-bit integer. 如果编译器已经支持64位整数,则使用QuadParrt。否则,使用LowPart和HighPart成员来存储64位整数。换句话来说,LARGE_INTEGER相当于64位无符号整型。 msdn帮助文件:https://msdn.microsoft.com/zh-cn/library/windows/desktop...
According to MSDN "Windows NT defines a LARGE_INTEGER data type that is a 64-bit integer created from an array of two longwords. A LARGE_INTEGER type is not the same as a quadword. The quadword is a true, nonportable, 64-bit integer data type; the Windows NT LARGE_INTEGER is a ...
使⽤LowPart和HighPart成员来存储64位整数。换句话来说，LARGE_INTEGER 相当于64位⽆符号整型。msdn帮助⽂件：其中LARGE_INTEGER的定义中出现了两个匿名结构，相当于 如果不介意代码的移植性，可以像这样：LARGE_INTEGER a;a.LowPart = 1;需要移植的话可以这样：a.u.LowPart = 1;这个可能会帮助到你：
