MEM_ADDRESS_REQUIREMENTS structure (winnt.h)

  • Article
  • 2 minutes to read

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. Calling <a href=" and specifying NULL for LowestStartingAddress, and specifying NULL for LowestStartingAddress, gives the same behavior as calling VirtualAlloc/MapViewOfFile.

HighestEndingAddress

Specifies the highest acceptable address (inclusive). This address must not exceed lpMaximumApplicationAddress returned by GetSystemInfo. Calling <a href=" and specifying NULL for LowestStartingAddress, and specifying NULL for HighestEndingAddress, gives the same behavior as calling VirtualAlloc/MapViewOfFile.

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.
