LARGE_INTEGER union

Applies to: desktop apps | Metro style apps

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;
  };
  struct {
    DWORD LowPart;
    LONG  HighPart;
  } u;
  LONGLONG QuadPart;
} LARGE_INTEGER, *PLARGE_INTEGER;

Members

LowPart

The low-order 32 bits.

HighPart

The high-order 32 bits.

u

LowPart

The low-order 32 bits.

HighPart

The high-order 32 bits.

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.
