Return Value: If the function sets the delay time successfully, it will return 0. If any error,
the function returns –1.
3. Syntax:
i32 setSoftOffDelayM( u32 setTime )
Description: The Soft Off Delay is the interval between that the system receives a
power off signal and that the system generates a power off signal. This function sets up
the interval in minutes.
Parameters: The parameter is of the type of unsigned long. The value of the parameter
