LARGE_INTEGER

The LARGE_INTEGER structure is used to represent a 64-bit signed integer value.

typedef union _LARGE_INTEGER { 
    struct {
        DWORD LowPart; 
        LONG  HighPart; 
    };
    LONGLONG QuadPart;
} LARGE_INTEGER; 
 

Members

LowPart

Specifies the low-order 32 bits.

HighPart

Specifies the high-order 32 bits.

QuadPart

Specifies a 64-bit signed 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.
