3.16 SysDisablePowerOff

This function disables turning off the power with the Power key. In case where turning off the power

has been set disabled, PBT_APMSUSPEND of WM_POWERBROADCAST will be issued when

the Power key is pressed. In your application, design the application so that this message is retrieved

to precede necessary routine works before turning soft-off on the terminal. See also notes below.

In the Device Emulator, the function does not perform, but stores the preset value as internal

variable. The value stored can be checked with SysGetPowerOff function.
