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.
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;
QuotedwLength
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.
