MEMORYSTATUS

  • Article

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

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 0 and 100 that gives a general idea of current memory utilization, in which 0 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. Note that this number does not represent the actual 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.
