CntZeroClearCount

Function

Clears the count value to 0. Supports multi-processing.

Format

Ret = CntZeroClearCount ( Id , ChNo , ChNum )

Parameters

Id [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify the device ID retrieved from CntInit.

ChNo [ VB.NET: Short ] [ C, C++: short * ] [ C#: out short ] [ Python: ctypes.POINTER(ctypes.c_short) ]
Specify the base address of array storing the setting channel number.

ChNum [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify the number of channels in array ChNo.

Return Value

Ret [ VB.NET: Integer ] [ C, C++: long ] [ C#: int ] [ Python: ctypes.c_long ]

Definition	Value	Description
CNT_ERR_SUCCESS	0	Normality completion
CNT_ERR_SYS_RECOVERED_FROM_STANDBY	7	Execute the function CntResetDevice to return from the standby mode.
CNT_ERR_DLL_INVALID_ID	10001	Invalid ID was specified.
CNT_ERR_DLL_CALL_DRIVER	10002	CNT driver can't be called (Failed in the device I/O control).
CNT_ERR_DLL_BUFF_ADDRESS	10101	Invalid data buffer address.
CNT_ERR_SYS_NOT_SUPPORTED	20001	This function can't be used by this device.

Initial Value

None

Remarks

Clears the count value of specified channel to 0. Passes the channel number in array. This function is valid before or after the counter starts.

Example

Clears the count value of channel 0 and channel 1 to 0.

VB.NET	Dim Ret As Integer Dim ChNo(1) As Short ChNo(0) = 0 ChNo(1) = 1 Ret = CntZeroClearCount ( Id , ChNo , 2 )
C, C++	long Ret; short ChNo[2]; ChNo[0] = 0; ChNo[1] = 1; Ret = CntZeroClearCount ( Id , ChNo , 2 );
C#	int Ret; short[] ChNo = new short[2]; ChNo[0] = 0; ChNo[1] = 1; Ret = cnt.ZeroClearCount ( Id , out ChNo , 2 );
Python	Ret = ctypes.c_long() ChNoType = ctypes.c_short * 2 ChNo = ChNoType() ChNo[0] = 0 ChNo[1] = 1 Ret.value = ccnt.CntZeroClearCount ( Id , ChNo , 2 )
