3/28/2014

This structure contains information about current memory availability. The GlobalMemoryStatus function uses this structure.

Syntax

typedef struct _MEMORYSTATUS {
  DWORD dwLength;
  DWORD dwMemoryLoad;
  DWORD dwTotalPhys;
  DWORD dwAvailPhys;
  DWORD dwTotalPageFile;
  DWORD dwAvailPageFile;
  DWORD dwTotalVirtual;
  DWORD dwAvailVirtual;
} MEMORYSTATUS, *LPMEMORYSTATUS;

Members

  • dwLength
    Specifies the size, in bytes, of the MEMORYSTATUS structure.

    Set this member to sizeof(MEMORYSTATUS) when passing it to the GlobalMemoryStatus function.

  • dwMemoryLoad
    Specifies a number between zero and 100 that gives a general idea of current memory use, in which zero indicates no memory use and 100 indicates full memory use.
  • dwTotalPhys
    Indicates the total number of bytes of physical memory.
  • dwAvailPhys
    Indicates the number of bytes of physical memory available.

  • dwTotalPageFile
    Indicates the total number of bytes that can be stored in the paging file.

    This number does not represent the physical size of the paging file on disk.

  • dwAvailPageFile
    Indicates the number of bytes available in the paging file.
  • dwTotalVirtual
    Indicates the total number of bytes that can be described in the user mode portion of the virtual address space of the calling process.
  • dwAvailVirtual
    Indicates the number of bytes of unreserved and uncommitted memory in the user mode portion of the virtual address space of the calling process.
