PWLX_USE_CTRL_ALT_DEL callback function (winwlx.h)

Called by GINA to tell Winlogon to use the standard CTRL+ALT+DEL key combination as a secure attention sequence (SAS).

Note   GINA DLLs are ignored in Windows Vista.
This function has been superseded by the WlxSetOption function called with Option parameter set to WLX_OPTION_USE_CTRL_ALT_DEL.
