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.
