Specifies a lowest and highest base address and alignment as part of an extended parameter to a function that manages virtual memory.
Syntax
typedef struct _MEM_ADDRESS_REQUIREMENTS {
PVOID LowestStartingAddress;
PVOID HighestEndingAddress;
SIZE_T Alignment;
} MEM_ADDRESS_REQUIREMENTS, *PMEM_ADDRESS_REQUIREMENTS;
Members
LowestStartingAddress
Specifies the lowest acceptable address. This address must be a multiple of the allocation granularity returned by GetSystemInfo, or a multiple of the large page size returned by GetLargePageMinimum if large pages are being requested. If this member is NULL, then there is no lower limit.
HighestEndingAddress
Specifies the highest acceptable address (inclusive). This address must not exceed lpMaximumApplicationAddress returned by GetSystemInfo. If this member is NULL, then there is no upper limit.
Alignment
Specifies power-of-2 alignment. Specifying 0 aligns the returned address on the system allocation granularity.
Remarks
Specifying a MEM_ADDRESS_REQUIREMENTS structure with all fields set to 0 is the same as not specifying one at all.
