ULARGE_INTEGER union

Represents 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.
 

Syntax

typedef union _ULARGE_INTEGER {
  struct {
    DWORD LowPart;
    DWORD HighPart;
  } DUMMYSTRUCTNAME;
  struct {
    DWORD LowPart;
    DWORD HighPart;
  } u;
  ULONGLONG QuadPart;
} ULARGE_INTEGER;

Members

DUMMYSTRUCTNAME

DUMMYSTRUCTNAME.LowPart

DUMMYSTRUCTNAME.HighPart

u

u.LowPart

u.HighPart

QuadPart

An unsigned 64-bit integer.

Remarks

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.
