FindFirstChangeNotification
..msdn    Add comment     W32 Constants      Translate this page
Creates a change notification handle and sets up initial change notification filter conditions.

A wait on a notification handle succeeds when a change matching the filter conditions occurs in the specified directory or subtree.
Code examples:
Monitoring changes in a directory
Declaration:
HANDLE FindFirstChangeNotification(
  LPCTSTR lpPathName,    // directory name
  BOOL bWatchSubtree,    // monitoring option
  DWORD dwNotifyFilter   // filter conditions
);
FoxPro declaration:
DECLARE INTEGER FindFirstChangeNotification IN kernel32;
    STRING  lpPathName,;
    INTEGER bWatchSubtree,;
    INTEGER dwNotifyFilter
Parameters:
lpPathName
[in] Pointer to a null-terminated string that specifies the path of the directory to watch.

bWatchSubtree
[in] Specifies whether the function will monitor the directory or the directory tree.

dwNotifyFilter
[in] Specifies the filter conditions that satisfy a change notification wait.
Return value:
If the function succeeds, the return value is a handle to a find change notification object.
My comment:
The wait functions can monitor the specified directory or subtree by using the handle returned by the FindFirstChangeNotification function:

SignalObjectAndWait, WaitForSingleObject, WaitForSingleObjectEx, WaitForMultipleObjects, WaitForMultipleObjectsEx, MsgWaitForMultipleObjects, MsgWaitForMultipleObjectsEx.
