i use code as below:  
void CallMyHeavyTreatpments(void)  
{  
// To store remaining time before the end of watchdog inactivation  
u32 i\_u32\_ReaminingTime;  
// Watchdog inactivation for 30 seconds  
adl\_wdPut2Sleep(ADL\_TMR\_S\_TO\_TICK(30));  
// Watchdog reactivation  
i\_u32\_ReaminingTime = adl\_wdAwake();  
printf(“Watchdog is to be awaken in %d number of ticks”,  
i\_u32\_ReaminingTime );  
}  
but get 0 number of ticks?
