Below is my test program, nothing special:
/* test change notification */
#include <windows.h>
#include <stdio.h>
int main()
{
DWORD dwWaitStatus;
HANDLE dwChangeHandles[1];
dwChangeHandles[0] = FindFirstChangeNotification(
"i:\\TEST", // directory to watch
FALSE, // do not watch the subtree
FILE_NOTIFY_CHANGE_FILE_NAME); // watch file name changes
if (dwChangeHandles[0] == INVALID_HANDLE_VALUE)
exit(GetLastError());
printf("Starting change notification\n");
// Change notification is set. Now wait on both notification
// handles and refresh accordingly.
while (TRUE) {
dwWaitStatus = WaitForMultipleObjects(1, dwChangeHandles,
FALSE, INFINITE);
printf(".");
switch (dwWaitStatus) {
case WAIT_OBJECT_0:
if (FindNextChangeNotification( dwChangeHandles[0]) ==
FALSE )
exit(GetLastError());
break;
default:
printf( "Change notify failure\n");
exit(0);
break;
}
}
return 0;
}
I can't tell you if the change I made to reply.c completely solves my
problem , I'll need to test this at work.
But what I found out would explain the effects I had.
