LARGE_INTEGER union (winnt.h)
Represents a 64-bit signed 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.
Syntax
typedef union _LARGE_INTEGER {
struct {
DWORD LowPart;
LONG HighPart;
} DUMMYSTRUCTNAME;
struct {
DWORD LowPart;
LONG HighPart;
} u;
LONGLONG QuadPart;
} LARGE_INTEGER;
Members
DUMMYSTRUCTNAME
DUMMYSTRUCTNAME.LowPart
DUMMYSTRUCTNAME.HighPart
u
u.LowPart
u.HighPart
QuadPart
A signed 64-bit integer.
Remarks
The LARGE_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.
