The ULARGE_INTEGER structure is used to specify a 64-bit unsigned integer value.
Note Your C compiler may support 64-bit integers natively. For example, Microsoft® Visual C++® supports the __int64 sized integer type. For more information, see the documentation included with your C compiler.
typedef union _ULARGE_INTEGER { struct { DWORD LowPart; DWORD HighPart; }; ULONGLONG QuadPart; } ULARGE_INTEGER, *PULARGE_INTEGER;
The ULARGE_INTEGER structure is actually a union. If your compiler has built-in support for 64-bit integers, use the QuadPart member to store the 64-bit integer. Otherwise, use the LowPart and HighPart members to store the 64-bit integer.
