GlobalMemoryStatusEx函數用於擷取系統記憶體資訊:

BOOL WINAPI GlobalMemoryStatusEx(
  __inout  LPMEMORYSTATUSEX lpBuffer
);

範例程式碼:

void CTestDlg::GetMemoryInfo()
{
 MEMORYSTATUSEX statex;

 statex.dwLength = sizeof (statex);

 GlobalMemoryStatusEx(&statex);

 CString strInfo = "記憶體:\r\n";
 CString strTemp = "";
 // 記憶體使用量率
 strTemp.Format("There is  %ld percent of memory in use.\r\n", statex.dwMemoryLoad);
 strInfo += strTemp;
 // 實體記憶體
 strTemp.Format("There are %I64d total Kbytes of physical memory.\r\n", statex.ullTotalPhys/1024);
 strInfo += strTemp;
 // 可用實體記憶體
 strTemp.Format("There are %I64d free Kbytes of physical memory.\r\n", statex.ullAvailPhys/1024);
 strInfo += strTemp;
 // 認可用量:總數
 strTemp.Format("There are %I64d total Kbytes of paging file.\r\n", statex.ullTotalPageFile/1024);
 strInfo += strTemp;
 // 認可用量:未用
 strTemp.Format("There are %I64d free Kbytes of paging file.\r\n", statex.ullAvailPageFile/1024);
 strInfo += strTemp;
 // 虛擬記憶體
 strTemp.Format("There are %I64d total Kbytes of virtual memory.\r\n", statex.ullTotalVirtual/1024);
 strInfo += strTemp;
 // 可用虛擬記憶體
 strTemp.Format("There are %I64d free Kbytes of virtual memory.\r\n", statex.ullAvailVirtual/1024);
 strInfo += strTemp;
 // ullAvailExtendedVirtual保留欄位
 strTemp.Format("There are %I64d free Kbytes of extended memory.\r\n", statex.ullAvailExtendedVirtual/1024);
 strInfo += strTemp;

 m_staticMemory.SetWindowText(strInfo);
}
