Monitoring thread may also be specified (the default is THREAD_PRIORITY_LOWEST):Ĭopy Code // Start monitoring a path // When the disk space drops below a defined threshold // a message is sent to the specified window //īOOL Start( const CString& sPath, // Path to monitorĭWORDLONG dwThreshold, // Send notification when space // drops below this value

The Start() method starts monitoring a specified path.Īlong with the path to monitor, the free space threshold must be specified,Īnd (optionally) a target window and message. Such dependencies, and done it the hard way myself. To make the code as widely applicable as possible, I've deliberately avoided If you're running on a platform without it (i.e.

is only available on systems with version 4.71 or later of Shell32.dll. SHGetDiskFreeSpace() function (which performs this voodoo for you) It's worthy of note here that the latest recommended way of doing this - the RdwFreeSpace = dwFreeClusters * dwSectorsPerCluster * dwBytesPerSector Failing that try the old fashioned way. RdwFreeSpace = nCallerFreeBytes.QuadPart ULARGE_INTEGER nTotalFreeBytes // Receives the total free bytes on // the disk ULARGE_INTEGER nDiskSize // Receives the number of bytes on disk ULARGE_INTEGER nCallerFreeBytes // Receives the number of bytes on // disk available to the caller (LPFNGETSPACE)::GetProcAddress(hKernel, ' GetDiskFreeSpaceA' ) (LPFNGETSPACEEX)::GetProcAddress(hKernel, ' GetDiskFreeSpaceExA' ) (LPFNGETSPACE)::GetProcAddress(hKernel, ' GetDiskFreeSpaceW' ) (LPFNGETSPACEEX)::GetProcAddress(hKernel, ' GetDiskFreeSpaceExW' ) HMODULE hKernel = ::GetModuleHandle( _T( ' Kernel32.dll') ) Load the kernel to gain access to the functions we want // If this fails, something's REALLY wrong. The (rather messy) details of this are buried in the GetFreeDiskSpace() method:-īOOL CNGDiskSpaceMonitor::GetFreeDiskSpace( const CString& sPath,

#Monit disk space windows

System of the original Windows 95 release anyway) can't be read accurately. Of this being that disks over 2GB in size (which aren't supported by FAT16 file If not, GetDiskFreeSpace() is used instead the consequence In order to remain portable, the class uses explicit linking to determine whether GetDiskFreeSpaceEx() is available. GetDiskFreeSpaceEx() function - is not available on all Win32 platforms (it was introduced in Windows 95 OSR2). The problem is that the preferred method - the Reading the free disk space on a Windows machine is one of those tasks which Sleep for a little while between polls. Managed to read the disk space OK if (m_dwFreeSpace 0) If (GetFreeDiskSpace(sPath, m_dwFreeSpace) ) Stop monitoring if the target window dies break If ( (NULL != m_hwndTarget) & !::IsWindow(m_hwndTarget) ) // Note that the timeout is set to zero so the wait // will return IMMEDIATELY if (WAIT_OBJECT_0 = ::WaitForSingleObject(hEvent, 0)) Check if the event has been signaled // If so its time for this thread to die. Copy Code // Loop until a the available space drops below the threshold or hEvent // (m_Event) becomes set indicating it's time for the thread to end.
