5.43  _9111_AD_FFHF_INT_Restart 

@ Description  

After calling _9111_AD_FFHF_INT_Start, the AD conversion and transfer 
won’t stop until the N blocks of conversion have been completed. After the 
N blocks of AD data are acquired, calling this function can restart the 
FIFO half full interrupt transfer without re-initial all the relative registers. 
However, if _9111_AD_INT_Stop has been called, the program should 
use _9111_AD_FFHF_INT_Start to restart interrupt transfer function.     

@ Syntax  

C/C++ (DOS) 

U16 _9111_AD_FFHF_INT_Restart (U16 cardNo) 

C/C++ (Windows 95) 

U16 W_9111_AD_FFHF_INT_Restart (U16 cardNo) 

Visual Basic (Windows 95) 

W_9111_AD_FFHF_INT_Restart (ByVal cardNo As Integer) As 
Integer 

@ Argument 

cardNo: the card number of PCI-9111 card initialized. 

@ Return Code  

ERR_NoError
