// Define timeout type - represents timeout value in seconds
//
typedef ULONG TIMEOUT;
typedef TIMEOUT * PTIMEOUT;
//
// Define special timeout values
//
// The top bit of the timeout value is the 'notify bit'.
// This bit is only used when the timeout value = TIMEOUT_NONE
//
// When a screen-saver timeout occurs, the timeout stack is searched
// from the top down for the first occurrence of
// 1) A window with a timeout OR
// 2) The first TIMEOUT_NONE window with the notify-bit set.
//
// In case 1), the window is timed-out and returns DLG_SCREEN_SAVER_TIMEOUT.
//
// In case 2), a WM_SCREEN_SAVER_TIMEOUT message is posted to the window.
//
// The notify bit is never inherited. If required, it must be specified in
// addition to TIMEOUT_CURRENT.
//
// NOTE SAS messages are always sent to the topmost timeout window
//
// NOTE User logoff messages cause the top window to return DLG_USER_LOGOFF
// if it has a non-0 timeout, otherwise the window receives a WM_USER_LOGOFF
// message.
