Return code.

Remarks

This hook is called to notify applications that the system is rebooting due to a Ctrl+Alt+Del sequence being entered. It enables applications to write existing information to the hardfile immediately, avoiding loss of data before the system reboots.

Note: Do not use any of the Win or Gpi functions inside the hook routine. At the point in time that the hook routine is executing, these sub-systems may not be fully available because they might be partially shutdown.
