Question about variables defining

[Graveyard]

Hello , this question may be obvious for most of you but i really couldn't find any additional details .
So in the (ram info.exe) example the MEMORYSTATUS structure for the GolbalMemoryStatus function is defined like that what does that mean.
(memstat   MEMORYSTATUS <sizeof MEMORYSTATUS,?,?,?,?,?,?,?>)

Check the MEMORYSTATUS docs. The first element of the structure is its size.

Code Select Expand

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


dwLength

The size of the MEMORYSTATUS data structure, in bytes. You do not need to set this member before calling the GlobalMemoryStatus function; the function sets it.
