ULARGE_INTEGER

The ULARGE_INTEGER structure is used to specify a 64-bit unsigned integer value.

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

Members

LowPart

Specifies the low-order 32 bits.

HighPart

Specifies the high-order 32 bits.

QuadPart

Specifies a 64-bit unsigned 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.
