The EnumDesktopWindows function enumerates all windows in a desktop by passing the handle of each window, in turn, to an application-defined callback function.
BOOL EnumDesktopWindows(
HDESK hDesktop, |
// handle to desktop to enumerate |
WNDENUMPROC lpfn, |
// points to application’s callback function |
LPARAM lParam |
// 32-bit value to pass to the callback function |
); |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
The EnumDesktopWindows function repeatedly invokes the lpfn callback function until the last window is enumerated or the callback function returns FALSE.
